the effect of temperature on a tennis ball experimentthe effect of temperature on a tennis ball experiment

(Incorporation, 2011)The first rubber tennis balls were made out of pure rubber, and their properties were increased by stitching flannel on to the core. Hot temperatures create more pressure whereas cold temperatures do not produce much pressure. Any type of extreme temperature, whether hot or cold, will cause undue wear on the strings. (2011). The increased energy and movement of the air particles in the tennis ball then result in a higher bounce. But how much higher or lower? Table 1 Percentage change in stiffness between temperature spans. As such, gas molecules can easily expand or contract. Stiffness is the most important property of strings. Ball History. In warm temperatures, the opposite is true. Thermometer What is so dramatic during this post-tensioning-heating phase is that there is only tension reduction, not a competition between tension increase and relaxation, as there is during tensioning. Six tennis balls Have another person measure and record how high the ball bounces. University of Virginia Physics Department, n.d. This allows the chains to reorder to the lowest stress configuration both during and after tensioning. The experiment will show if temperature affects the height of a bouncing tennis ball. (Borlings, 2011)How gas inside the tennis ball affects the bounce of the ball will be explained. http://www.how-2-tennis.com/history-of-tennis-balls.html, http://www.livestrong.com/article/398740-temperatures-tennis-balls/, http://www.itftennis.com/technical/equipment/balls/history.asp, http://www.livestrong.com/article/401050-does-temperature-affect-how-high-a-tennis-ball-will-bounce/, Find a tennis ball, and put it inside a freezer for about 20 minutes with a thermometer next to it. The scientific equation for determining the pressure of gas is p=rRT, where p is the pressure, r is the density, R is a constant specific to the gas and T is temperature. Natural gut string is generally more responsive to changes in temperature. The part of a paintball gun that is used to shoot the ball accurately is the barrel. Tennis serve is the shot that starts off the point. Mark a point 1 metre from the ground on a wall. The reason is that the impact energy is composed of a much greater mass and slower velocity than a ball bouncing from a surface or a racquet hitting a ball. Figure 3 Tension vs time for the same string as Figure 2 but following the heating-after-tensioning protocol. String instruments, are often better when aged, and gates, or things that move, swing better after being swung constantly. The Temperature of Tennis Balls. Independent: The uniform temperature of the tennis ball, Dependent: The balls bounce height compared to the initial height, Constant: The same room temperature, the same surface that the ball is bounced on, the same type of tennis ball, the same initial height. Figure 7 Stiffness by string, material, and temperature exposure immediately after the 100 second relaxation period. Stiffness is the property that measures the result of all these elongation, duration, and relaxation processes. A tennis ball is designed as a hollow rubber core with pressurized air. Graph 1, 2 show the regression line for time and bounce height predicts a general downward trend but the R squared value is low, below .17 in both cases. 28 Oct. 2014. Signature: ___________________________________________________. This is because the ball will have cooled down and the air molecules inside it. Later, the data would be compared by calculating the percentage of the bounce height over the initial height. It is the net result of the effects of elongation, tension, strain rate and temperature. The "take-away" is twofold: First, if you like firm/stiff playing strings, do not expose them to higher than usual temperatures after stringing. When you have heated the balls, you will have provided them more energy to move about, and as such, they will be able to bounce to higher heights when they are dropped to the ground. Purpose The purpose of this project is to determine how tennis balls are affected by different temperature conditions. Hold the meter stick vertically with one end on the ground. With this, it will look at the movements that occur at each of the upper extremity together with the muscles that are in use at the joints. Hold a ball so its lowest point is at the 1 metre point. The green represents the felt on the ball, and the black represents the hollow core. Your email address will not be published. The experiment had four different temperature 12 , 51 , 75 , 111 . In general, players can compensate by adjusting playing style as well as making technical tweaks to their rackets and stringing configurations. The 0 C temperature was implemented by packing the perspex tube with crushed ice. The balls need to have the right temperature and air pressure inside in order to work best. (Sheehan, 2011)Also, as most people know, the molecules that make up gas can easily expand or contract. Figure 10 Closeup of elongation vs temperature for each nylon and polyester string. Racquetball is played on a rectangular indoor court with four side walls and a ceiling. If the density and the constant remain the same, a higher temperature results in higher pressure, while a lower temperature results in lower pressure. Gas molecules are generally unorganized; they easily slide around and over one another to fill up any space they occupy. In this experiment, one will put the tennis ball at four different temperaturesroom, freezing, hot, and cold. Analysis of the data will either conclude that the common practices of opening a new can balls often is necessary to keep a consistent bounce height, or show that it is unnecessary and balls out of cans previously opened bounce with the same height as newly opened cans. The balls which were placed in a freezer had a bounce percentage of 54.90. How does Temperature Affect the Bounce of a Tennis Ball? Even amateur players consider the effects important enough to open a new can every couple of days. Tension loss is due to the reordering of molecular bonds to the lowest stress equilibrium available at any given moment. Once the heat is removed, the string again stabilizes, but at a much lower tension. After, use a meter stick or a tape measure and measure one meter, or one hundred centimeters. Thus, each string at 0 C was stiffest, followed by 20 C and 40 C (Figure 7). Effect of Temperature on Strings. Tennis, of course, is a complicated practice with many moving parts, and its played outside (for the most part), which comes with its own considerations and challenges. (Incorporation, 2011)In the late 1920s, tennis balls became pressurized. Hot temperatures create more pressure whereas cold temperatures do not produce much pressure. Once the arm has begun to accelerate towards the ball, the tricep brachii is then used to, The ball uses this kinetic energy to move up the usually 6 to 7 degree incline to the top of the playing field. In the study, they considered strings of different materials under different temperatures. An experiment was performed to determine the effect of temperature on the stiffness, elongation, tension loss and maintenance of tennis strings. The expected result was that the tension loss would increase for each string by about the same amount, regardless of whether it was heated before tensioning or after tensioning. Crawford Lindsey, Tennis Warehouse, San Luis Obispo, CA. Try comparing a baseball to a golf ball or a tennis ball. Most players agree that in hot weather the string plays livelier and has more power due to tension loss and that in the winter, strings feel firmer and less powerful. It is the interplay between stretch rate, stretch amount, stretch duration, temperature, and stress relaxation that effects the amount of tension loss that occurs only in the relaxation period (the period that was measured to get "tension loss"). While we think primarily about the effect of temperature on rackets and their strings, theres one thing that is also significantly affected by high temperatures: the balls themselves. This increased energy and movement results in a higher bounce. The residuals vs. time graphs 17, 18 and residuals vs. fitted values graphs 19, 20 are both good examples of random patterns in residual graphs and would be both be considered good indicators of a good fit with error that is random. The hypothesis was supported. Her professional writing works focus mainly on the subjects of physical health, fitness, nutrition and positive lifestyle changes. Stand on the chair and place the tape measure next to you. America seemed very separated from the game until a sweep of popularity in California in 1989. Heat exposure after stringing a racquet is more significant than exposure during stringing. An increase in R squared to values of 0.974 and 0.957 were seen and suggests that the quadratic fit is even better than the linear one. This act is attained underhand or overhead. When a tennis ball is compressed, its internal air pressure is boosted. Here is the data collected from the first bounce of each temperature. 3.Oven was preheated to 100oC. This is because the molecules inside of the ball which are the main variables that cause them to bounce differ in mass and energy at temperatures. As you will notice from your experiment, the balls that have been treated to the ice chest with ice in it will tend to have lower bounces, resulting from the molecules moving around less and containing less energy. With such a low R squared value, the regression line does not predict many of the points and can not be considered a good fit to the relationship. The air molecules inside the ball will also move around slowly and tend to have less energy when the ball has been cooled down, meaning that the ball will have a lower bounce when you drop it to the ground. The paper will focus on the some of the types of the serves and the ways in which the upper extremity are involved in the game. (Sheehan, 2011)Its just like a trampoline: When one jumps on a trampoline, the material one the trampoline expands and stretches, and when it does, the trampoline is forced to come back up to its original state, causing one to bounce on the trampoline. Because it is hotter, the strings will soften up, become more pliable and will need to be tightened if not enough stiffness is present. Electrical tape Place four tennis balls in a freezer, four in a refrigerator, four at room temperature and four outside in the sun. As long as there is stress, some molecular bonds will continue to reorient to less stressful positions given enough time. This showed that the non-championship ball was more consistent than the championship ball in the test. It is also an ideal learning opportunity that can show us how the effects of temperature cause variations in the bouncing ability of a tennis ball. (Incorporation, 2011) This method was used for a long time. Retrieved 8 24, 2012, from Wikipedia: http://en.wikipedia.org/wiki/Tennis_ball, Your email address will not be published. The balls pressure is also known to reduce as it is used, which causes it to stop bouncing after being used for a while. If the uniform temperature of a tennis ball is decreased, the balls bounce will be lower. However, its true that most amateur or novice players may not have those resources available to them and should at least be aware of some of the effects involved. The analysis of all the data proves some of the questions posed. Percentages of the tennis balls bounce. Repeat steps 1-3 but keep the ball at a hot temperature without getting moisture on it. A residual analysis was next completed for the liner regression. In doing this, high percentages of the efforts are normally exerted at the upper extremity of the body, while the rest at the lower extremity of the body. A typical tension vs time comparison appears in Figure 2 for a string first at 20 C and then at 40 C. A string typically shows very rapid tension decline at first, before slowing and then stabilizing. Other conclusions will try to prove what the optimum playing temperature and humidity is, and if these factors affect the speed of the game. Record it. When the temperature increases, the gas molecules inside the tennis ball expand. Experiment. The more extended height from which you drop off the balls is also helpful and means that you can make more accurate observations. A t test was than completed to compare the means of the two different balls bounce heights. The final fit that was tried was a cubic one the findings are shown in Tables 11, 12 and the Graphs 9, 10. (Harriman, 2012). After ten games, tennis balls are known to have a rebound ratio of less than 53%. This is because the higher temperatures within the summer cause the balls to bounce higher. Setup #1 Tension vs timing of heat application. While nylon and polyester are less durable than nylon and responsive to unfavorable conditions, they are still more robust than natural gut. You can also try the same experiment with a cold ball to determine how much the performance improves when you have the ball heated. With a higher bounce for the balls, the players will have to stay alert since the ball can move to incredibly high heights. Repeat steps 1-3 but keep the ball in a refrigerator. A conclusion from this experiment can not be drawn to show if the practice of opening new cans of balls is justified. This allows more elongation at lower stresses than occur at lower temperatures. Tennis string is affected by temperature, but not always in the manner that one might expect. But if the tennis ball is heated it will have the opposite affect. A good example of this would be, when designing buildings to survive in areas where earthquakes happen frequently. After the tennis ball reforms into its original shape, the gas inside the ball pushes back up and causes the ball to bounce into the air. The setup was essentially the same as in Figure 1 but a computer controlled stretching program was different. When the temperature increases, the gas molecules inside the tennis ball expand. The stiffness tests closely approximated the expected result that stiffness would have an inverse relationship to increase in temperature. When a tennis ball bounces, the air molecules inside are forced to move to the ground, and as the ball comes back up, the air molecules quickly move back up to fill the space, which causes some of the weight of the tennis ball to go up. One may also use a heat dish to do this. Temperature Cubic ANOVA. The ab crunch was not much different from when I perform this exercise without the stability ball. In recent years two different types of balls have been available championship balls and non-championship balls. Bocce ball, which was first documented in the year 5200 B.C., is a sport that was first popularized during the roman empire. The question of concern was whether adding heat after stabilization would start (or accelerate) tension loss. A string was secured between two clamps 200 mm apart at start and running through a clear perspex tube with rubber plugs in each end. Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. The tennis balls which were placed in a boiling environment had an average bounce percentage of 83.33. Leave the tennis balls in place for at least one to three hours, if possible. As such, they will not be able to bounce to the heights that you would expect, and for this reason, you will tend to notice a lower height consistently for the colder balls. Why Is String Stiffness So Important To Power? A further study should be completed to see if anything else effects the balls differently to try and determine what makes the balls different. Using balls that are all new means that your experiment will be more consistent, and as such, you will be able to get the best kind of results. Figure 9 Elongation by temperature in setup #2. Two different types of balls, Penn Championship and Non-Championship will be compared. Copyright 2023 Elite Tennis Guide | All Rights Reserved. Tension Loss. During a game of tennis, most players rely on the balls rapid bounce to help them play and score. The bladders are usually made of rubber or rubber like things. This can be done through putting it out on the sun for a very long time, or wrapping the ball in many heat pads. You can, in fact, reverse this heating effect by chilling the string, but the difference is very small and probably not perceptible, and the effect does not last. Tennis balls were first made in the early 1300s. The bladder inside the ball is what holds the air. co2 is carbon dioxide and carbon dioxide is an expanding gas. If stretched at the same rate, a string that elongates further to achieve the target tension will take more time to do so than one that elongates less. Tension is a component of stiffness. The greatest effect observed in this experiment was that exposing a string to high temperatures after post-tensioning stabilization/relaxation has occurred (as in leaving the racquet in the car during hot weather) produces the greatest decrease in tension. (Sheehan, 2011)Outside of the ball is felt, which is the furry, yellow fabric on the surface of the tennis ball. Figure 8 Closeup of stiffness vs temperature for each nylon and polyester string. During the course of playing tennis, especially in competition settings, players often painstakingly consider all factors that have a shot at affecting their game. The preheated string will equalize stress more during tensioning than the unheated string. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Enter your email address to follow this blog and receive notifications of new posts by email. Higher temperature allows weak secondary bonds between the polymer chains to break. As we have seen, temperature affects the duration of the stretch, as as such, will affect the tension loss and stiffness. A warmer ball will bounce higher than a cold one. The ruler was placed firmly on the ground at 90 such that it stood as vertically as possible. Many athletes use basketballs, soccer balls, and volley balls to play their sports. Players will be able to use the conclusions in many ways. This means that the tennis ball becomes dead after ten games, and after that, it is in a bricked state, and for this reason, it can not be used anymore. Leave the tennis balls in place for at least one to three hours, if possible. The temperature regression was carried out last. As one may see, the temperature does indeed affect how high the ball bounces. We are guessing that heat makes the molecules move faster in the bouncy ball, which gives it more elasticity, but I did not find anything in my research of this project that confirms that fact. (Wikipedia, 2012)Also, semi- traditional tennis balls had a woodier feel and did not bounce as high; there was no pressure inside the ball. I thank Dr. Choi for teaching me how to do this assignment and my parents for buying tennis balls for me. This increases the time it takes to achieve the target tension. Players often wonder how storing their racquets in the trunk of their car during extreme hot or cold weather would influence tension and performance? The value of the test statistic was found to be 0.40997 with an alpha level of 0.05 the H0 hypotheses would not be rejected. For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder. Add up all the ten readings and divide them by ten to find the mean height to which each ball could bounce back to at a specific temperature. Tension was recorded throughout the process. Why don't you do an experiment. Temperature can be measured by. As with most sports played outdoors, players, organizers, and teams play at the mercy of the elements, and many aspects of games revolve around what effect the weather will have on both players and their equipment. From the things they can controllike diet, rest, and conditioning, to the things that are relatively less predictablelike weather conditions and temperature, good players are continually considering all eventualities. This means that the pressure is optimal for performance on the field. This machine measured string tension vs elongation. It is the relaxation that occurs both during and after the stretch that is significant. Do you know what mechanics are really behind the outer layer? But if heat exposure occurs after tensioning and stabilization, the molecules become agitated and begin to move relative to each other. As an experiment, you can try to heat a tennis ball and see how well it will bounce. Then, drop the ball from a height of one meter. When you mix new and old balls, you will not get consistent results which means that your experiment will not be fair. Bocce ball was steadily rising and falling in popularity, until a major resurgence in 1896, when it was admitted an olympic sport, and has been part of the summer olympics ever since. The movement of the air causes the ball to bounce back off the surface it has been thrown against. Then, analyze the information. Figure 8 presents just such a picture grouped by materials. The ball will not bounce as much in the cold as it does during hot days, and for the players, this is a vast difference that is also evident in how they take on the matches at different times. Heating the string, whether before or during tensioning increases the mobility of the molecule chains. Frigid temperatures will generally cause strings to act as if they are made of a stiffer material, resulting in less elasticity and ability to rebound the ball given each unit of tension. The stiffness, k, is calculated as k = dF/dx, where dF is the increase in the force when elongation increases by dx. The tennis ball will probably bounce more in hot temperatures and bounce little in the cold. Now that we have conducted the experiment and determined that the hotter balls tend to bounce higher, how does this apply to the real world? No conclusions can be drawn from this data because of such a high lack of fit. The thermocouple recorded the temperature. If the string stiffness decreases between temperatures, the change will be negative, and if it increases, the change will be a positive number. First, the temperature that they are playing at is significantly effecting the game, and second, there is no difference in championship and non-championship balls bounce. NOTE: IEEE WAS NOT AVAILABLE FOR CITATIONS, SUBMITTED TO SABIO ACADEMY TO MEET THE REQUIREMENTS OF THE SR 90 JUNIOR RESEARCH COURSE AT SABIO ACADEMY. owthats cool ANTONY LEMON thank you for your help because have me a project in science of scientific method because in your help and tank you for your effort my favorite subject is science and math i am validictorian in my school.THANK YOU FOR YOUR EFFORT. Temperature were Plotted in 15, 16 both again show similar patterns indicating a upward trend in the data and poor randomness, both would be considered poor indications of a good fit. A string was inserted inside clear perspex tube with two open ends and through a small hole in a rubber stopper at each end of the tube. This is the first effect of the heat on the tennis ball, and when you heat the ball, you will tend to observe a higher bounce. (Sheehan, 2011)However, if one lets the ball continue to bounce, it will bounce less high each time until it eventually just sits on the ground. The first setup (Figure 1) was used to measure tension vs time for strings with different temperature exposure histories. The results are not quite as tidy and a bit unexpected. The blue dots represent the gas molecules inside. But because stress relaxation occurs at varying rates both before and after achievement of target tension, the magnitude of tension loss during the relaxation period (i.e., after the racquet has been strung) does not necessarily correlate to the total relaxation that has occurred nor to the final stiffness of the string. The second apparatus was a materials testing machine (Figure 4). We just wanted to let you know that we got a lot of information from this. The stiffness of the gut and nylon strings seemed to be more sensitive to temperature than did the polyester and kevlar strings. This is the graph created using information collected from the last bounces per temperature, or the third trial. (Wikipedia, 2012)From the 18th century, tennis balls were formed by wounding strips of wool around a nucleus made by rolling strips into a tiny ball. From that data, the lengthwise stiffness of each string was calculated. Figure 3 shows a typical result for this process. You will also have a more comfortable time working out the heights to which the balls can rebound, and as such, your experiment will go on more easily. Thus it takes quick reaction time and reflexes to play at higher levels. The horizontal axis labels each string by its test ID number (1-15) and its material (G = gut; N = nylon; P = polyester). Take 2 tennis balls and put them in the slow cooker for 10 mins. This time, the ball can be heated for longer than 20 minutes. Tennis balls in the 1400s were quite similar to the first tennis balls, butthey were stuffed with chalk, sand, sawdust, or earth. You can get an idea of just how much by looking at the percentage difference in stiffness resulting from the temperature exposures. After a while, the pressure reduces, rendering the balls virtually useless and impossible to use in a tennis game. Many aspects of the game of Bocce ball can be relatable to the simple concepts of Newtons original three laws, from the balls hitting each other (Newtons third law), to throwing balls harder to increase the force and then slowing down (Newtons first and second laws). in my school i finish up in 2nd place thank u very much. And we saw in Figures 7 and 8 that stiffness is proportional to temperature. The Effect of Temperature, Time, and Humidity on the Bounce of Tennis Balls. The tennis ball was then dropped from various heights; 1, 1.5 and 2 meters above a hard surface, using a meter ruler, before it was dropped onto the ground and the resulting bounce height measured. Does Air Pressure Affect the Bounce of a Basketball? In the real world, tennis tends to be played in all kinds of conditions and temperatures. (Harriman, 2012)When the temperature increases, the gas molecules expand and as they expand, the energy of them increases, causing them to bounce more tempestuously. Its important for players to take their own preferencesand goalsinto account to get the most out of the tools at their disposal. You can also experiment within an enclosed space to ensure that the blowing wind does not affect the bounce of your ball. The difference in stiffness between temperatures for each string was greater for the nylon strings. This means that the hypothesis was supported because it stated that if the uniform temperature of a tennis ball is increased, then it will bounce higher. This will give you a visual presentation of the bounce heights and the temperatures, which means that determining whether hot or cold balls can bounce to a higher height will be a lot easier. There are two reasons for this. Figure 7 is qualitative in that the horizontal axis is simply the itemization of each string, and thus each curve does not demonstrate any quantitatively causative relationships. Does it matter when the string is exposed to a temperature extreme before, during, or after tensioning? As the molecules expand, their energy increases as they bounce around more erratically. She works in a neonatal intensive care unit (NICU) and her previous nursing experience includes geriatrics, pulmonary disorders and home health care. What mainly causes a tennis ball to bounce is all the pressure stored inside. Top "The Effect of Temperature on a Bouncing Ball." The Effect of Temperature on a Bouncing Ball. It is the only attempt where a player takes his time to position up, instead of reacting to an opponents shot. Most players focus on tension, but that is only useful in as much as it predicts stiffness, which is often the case for comparing an individual string at different tensions but not for comparing different strings to each other. How does temperature affect the bounce of a tennis ball? Do you know how a golf ball works? Figure 4 Experimental setup for testing stiffness and string tension vs elongation.
