ABSTRACT
The air pressure inside a basketball has the biggest affect on bounce. The purpose of conducting this experiment is to determine if a basketball with a greater air pressure (psi) inside the basketball will bounce higher. The hypothesis for this experiment is 'If air pressure is decreased inside the basketball, then the bounce height will decrease as well'. I have participated in numerous inflatable ball sport activities and from personal experience this has enabled me to make an opinion on the results of the experiment, which is expressed in the hypothesis. A video camera was set up on a tripod, this was the main means of collecting the information by recording the bounce of the basketball after being released from a height of 2.7 meters in front of a measuring stick. The experiment was commenced with the basketball inflated to 12 psi and then the psi was decreased by one unit until the basket ball was measuring zero psi. It was essential that at each level of psi the basketball was dropped three times to gather an average resulting in more reliable data. When conducting this experiment the findings revealed the hypothesis was proven correct. When the basketball had the greatest amount of psi (12) it bounced the highest with a average height of 186.7cm. When the basketball had the least amount of psi (zero) it bounced the lowest height of 16.7cm. The results of this experiment provide valuable information to basketball players as it identifies that having the right
Air pressure can indeed affect the distance that the football will travel. The data from the experiment proved that the more air pressure, or the more inflated the ball is, then the farther the ball will travel. When one tested the lowest air pressure, our results showed that a flat ball will not travel far at all when thrown at a consistent speed. When one inflated the ball only halfway, it traveled significantly farther than a fully deflated ball. Furthermore, when one inflated the ball to the regulated air pressure of the National Football League, it travelled farther than both the fully deflated and halfway deflated ball. The statistics also supported the hypothesis for this experiment. The averages correlated with the distance that
Performing under pressure is a huge mental component in basketball. One must perform gracefully under pressure in front of thousands of fans on a game-to-game basis. I ask myself if there anyway to prepare for these type of situations. I like the idea of recreating pressure situations in practice. I have been simulating game pressure situations during my practice of free-throws by adding consequences if I don’t make a certain percentage. On top of this, I like the idea of getting into a zone or a focused mental state and going through a repeatable routine on game day. With a consistent routine, there is less susceptibility to succumb to pressurized situations. The goal is to become so accustomed to a routine, thereby leaving no time to worry
In football the force of impact can be dangerous. Helmets are constructed to protect the brains of the players. Without this protection the player will receive major damage from the impact of the force. In this lab, students will construct a device that will protect an egg from the impact force from the drop. The egg acts as a substitute for the brain and the device is the “helmet” for the egg. The independent variable of this experiment is the trials; the dependent variables of this experiment are time and velocity. By using the laws of physics, students will construct an efficient device that will protect the egg from the harsh impact of force.
Can you bend it like Beckham? With the right training, skill, and knowing more about the soccer ball, the individual will! The soccer ball is a very interesting object. A soccer ball has to have a certain amount of air pressure in order to work properly. The air also affects the soccer ball’s flight. The soccer ball is also made of different kinds of material and has different sizes. In the next couple of paragraphs I will tell you more about a soccer ball and the air pressure.
Bocce ball is a great way to demonstrate the complex wonders of Newton’s three laws in a simple and understandable way. Bocce ball, which was first documented in the year 5200 B.C., is a sport that was first popularized during the roman empire. It wasn’t more than just a leisurely activity until the game found its way back into Italy, once the Roman empire collapsed. 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. Bocce has really become such a widespread sport because you can participate no matter how old, what your race is, or what gender you are. All you need to do is roll a ball. America seemed very separated from the game until a sweep of popularity in California in 1989. Today there is said to be 25,000,000 bocce ball players in the United States. Many aspects of the game of Bocce ball can be relatable to the simple concepts of Newton’s original three laws, from the balls hitting each other (Newton’s third law), to throwing balls harder to increase the force and then slowing down (Newton’s first and second laws). Throughout this essay, I will not only explain what each of Newton’s three laws mean, but provide a real life example of how it could relate to the game of bocce ball.
For this study, footballs filled with different gases, with air being the control group and helium, nitrogen, argon, and carbon dioxide being the independent variables, were shot 15 times from a Snap Attack Machine. The hang times in seconds of the footballs were recorded and placed on a spreadsheet in Microsoft Excel. There were 2 experiments. The first experiment had the footballs filled to 6 PSI and the second experiment had the footballs filled to 9 PSI. The change in PSI was suggested by a graduate student, helping the researcher, because the lower PSI in the first experiment caused the Snap Machine to shoot the footballs and produce results all over the place with no precision (see Table 1 and Graph 1). The second experiment provided more precise results because the Snap Machine could shoot the footballs better (see Table 2 and Graph 2). The first experiment results were nullified for the error. The means, standard deviations, and standard errors of
We can all agree that basketball is almost becoming popular around the world. So many people play this sport but do people know how basketball started and how it evolute throughout the years since basketball was borned? So like every other sports and creations, there has to be a inventor and in basketball there was a man by the name of Dr. James Naismith. “Created in 1891 in a Springfield, Massachusetts YMCA gymnasium has grown into a game played worldwide by more than 300 million people”(historybits.com). So this game has been out for a very long period of time with many changing of the rules in basketball throughout the history. When it was first played in the late 1800s, there were different rules and even different looking basketball. As for the rules, originally there would be 10 people on the court but it first started with 18 people on the court which after couple of years it changed to only 10 people. Substitution was also different and the rule for this was at first no one can enter until the next game. “The rule was changed in 1920 to allow a player to re-enter the game one time. In 1934, the rule was expanded to allow players to re-enter the game twice, and, in 1945 the rule was finally changed to permit players to return to the game an unlimited number of times”(hooptactics.com). The first basketball looked very alike a football but round. The backboards were made out of straight wood and the baskets were made out of peach baskets or square boxes. There was only
This experiment transpired because of a fascination with basketball. In inches, the tested variable was the basketball court surface that gave the basketball the most immense bounce. After testing each surface, the data got averaged out, and based on the statistics, the multi-purpose floor averaged .7 inches more colossal than the hardwood, and 3.7 more than concrete.
Introduction: The experiment being tested is worth conducting as it can help people decide which ball to get if they want a bouncy one, either it is expensive, cheap, big or small. One fact on balls is that they are different and they bounce differently and are used differently. A netball has thinner layers than what a basketball does, and a basketball is more used for bouncing that a netball.
The “Just Drop It” investigation was very informative and taught important lessons. The purpose of the experiment was to find the effect of a ball’s drop height on its return bounce height. The experiment was executed by dropping three different balls of different masses at 100, 75, 50, and 25 centimeters. The major finding was the return bounce height depended the most on the ball’s mass and from where it was dropped. The hypothesis that if it the ball was dropped from a higher drop points, it would have a greater bounce height was supported. Other researches had similar data but were never exactly the same. This is most likely because the reading of the return bounce was not exactly correct and neither was the drop height. One thing that
Since details about this ball are unavailable due to it being an older model, this data suggests that the ball is a 3-piece ball. Srixon and Wilson Staff were extremely close, with Srixon’s average bounce height being 158.9 cm and Wilson’s average bounce height 0.2 cm lower at 158.6 cm. These results are, again, to be expected due to the 3-piece design of these ball. However, the average bounce height of the Strata ball (152 cm) was a surprise as it was the third most expensive ball and had the lowest bounce height. Dunlop and Top Flite’s bounce heights were average, being 161cm and 156.4cm respectively.
The duration of the experiment was not nearly enough time to improve the vertical jump extensively. The amount of time the subject was given was 4 weeks, improvement takes time and 4 weeks, as shown in the results was not enough time. The random physical state of the subject is another weakness of this experiment. Before doing the experiment, the health sheet was created to reason for these errors, this can be located in table (which table). Some days the subject feel more tired due to lack of sleep, extra physical exercise (sports), more hungry or full stomach, less motivated, more active and random incidents. Table 1 B shows the reasoning’s and explains the decrease. Another weakness of this experiment is that it is only tested by one subject and not multiple. Some subjects are more active than other making them more likely to have better results, by having multiple subject’s errors such as physical state can be eliminated. For this investigation to have better results the next time it is performed, some improvement will have to be implemented. This investigation can be further enhanced by having multiple subjects, controlling more variables: height of the vertec, clothes and shoes, longer duration of the experiment, get professional information (interview with a trainer) and ensure the usage of the vertec. By doing so, no sudden events can disturb the experiment altering the results. These improvements would reduce errors that have occurred during the experiment. As a result, a more polished experiment and a more reliable result would be collected and
The more and more I look around I begin to see how physics are integrated into practically everything that we do. These things would surely go unnoticed without making a conscious effort to notice them. For example simple things like riding a bike, or driving a car, or playing catch with a son or daughter. Just as these activities are loaded with elements of physics, sports are also, especially basketball. Physics play a part in every aspect of the game, from dribbling, passing, and shooting, to things as simple as setting a screen. First we should take a look at the elements of dribbling.
Participating in basketball begins with picking which basketball shoes to wear. The purpose of a sports shoe is to improve performance or reduce the risk of injury (Fong, Hong & Li, 2007). While playing the game of basketball I’ve realized it is a sport that involves different types of shoes which help improve jumping, landing, cutting and much more. Basketball has its positives and negatives for every age group; it has good health benefits, but it also consists of moderate to high risk lower body injuries to the lower back, legs and ankles. There are different types of basketball shoes which consist of high tops, mid tops, low cuts, cushioned shoes, non-cushioned shoes, and other different combinations. The high tops basketball shoe will have a collar that goes above the ankle like a sleeve. The mid tops basketball shoe covers slightly above the ankle, but lower than high tops. The low cut basketball shoes don’t have a collar at all and they don’t cover the ankle. Shoes also vary by weight and outsole traction. Through my knowledge picking the shoe to wear is solely on your preference. Whatever shoe that you choose will have different advantages or disadvantages to them. The purpose of this literature review is to explore the variety of effects specific shoe types have on basketball athletes.
There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
