This experiment would be considered a fair test as the variables were controlled; the same ball in the same condition was used, it was dropped from the same height each time, no additional external force acted upon it and the accuracy of the readings were consistent. However there were a few minor elements which may have altered the results such the test no being done on the different days. This would have had a minor effect as the temperature alters the elasticity of rubber and causes wood and concrete to expand and contract. 10.2 Error Analysis Data such the inconsistency that can be seen when looking at the foam ball colliding with the wood surface, can be caused by elements of human error or unfair testing, such as the ball hitting the …show more content…
This hypothesises is correct for the tennis and hand ball but it was also found that the type of material the ball and the surface effects the height the ball rebounds to. This is shown when the ping pong ball and the foam ball was dropped onto the lino. 10.4 Recommendations This experiment could be improved doing the experiment on the same day as that would then make hundred percent a fair test. It could further be improved by using a height scale on a wall for more accuracy when reading the results along with this, the experiment could be extended by changing the height to measure whether the ball rebounds to similar height again. CONCLUSION The aim of this experiment was to investigate the bounce efficiency by studying the effect multiple different surfaces have of the rebound height of a ball. It was hypothesised that “smoother and harder nature surfaces will allow the ball to rebound higher”, the experiment was successful as a conclusion was made. It was proven that different surfaces effect the bounce of the ball as does the type of ball being bounced effects the rebound height of the ball therefore meaning the hypothesis was wrong. This experiment can be linked back into the use of everyday life such as developing safer playground for
The most significant information found in the post-experiment research is the information found in Caruso’s research that accounts for the swing of the arms when jumping vertically. Caruso’s experiment shows how male and female volleyball players display different vertical jump heights with the men’s being higher. She accounts for this by saying the swing of the arms results in the men being able to jump higher due to their greater upper body strength.
Baseball is a fascinating sport that is exceptionally fun to play. This assignment is all about understanding the physics of a few key aspects of this sport. One might ask what physics could have to do with baseball? Like most sports baseball involves physical motion. Baseball encompasses all three planes of motion through throwing, hitting, and fielding. All of the classical laws of mechanics can be applied to understand the physics of this game.
When one throws a softball, it will always form some sort of a parabolic shape. However this shape is affected by the person throwing the ball and the distance at which the ball is thrown. The data that is shown in the graphs and equations below are from three different individuals, ranging in skill and distance. Two of these players were seasoned players and one was an inexperienced softball player. The distances from which they threw were 40 feet, 60 feet, and 80 feet. The three graphs below represent the softball throws done by a veteran softb...
Though the sport is based mostly in talent, or how the athlete utilizes these tools, equipment is critical for the performance of the athlete. Athletes seek bats that will increase their probability for a home run, maximize their hitting power, decrease the amount of energy loss in the collision for a greater ball velocity, and allow for a quicker swing, seeing as these factors are crucial to the success of their careers. Decades and decades of testing and experimentation have gotten the baseball bat to where it is. It first started as a simple plank, but with the growing popularity of the sport along...

This investigation aims to determine the ideal air pressure inside and the ideal material of a ball in order for that ball to achieve its greatest bounce height. This report will be focusing on how the air pressure and material of a soccer ball, basketball and volleyball affects the bounce height of each ball.
There is also the potential of human error within this experiment for example finding the meniscus is important to get an accurate amount using the graduated pipettes and burettes. There is a possibility that at one point in the experiment a chemical was measured inaccurately affecting the results. To resolve this, the experiment should have been repeated three times.
to stop the ball at the top of its bounce - so how could you measure
Consider the meaning of “fair”. What impact does fairness--perceived or actual--have in society and your life? Has fairness ever helped or hurt you personally? At what cost or benefit to you or others? (Washington and Lee University)
· I will change the height and measure the drop of the ball from at
James Naismith, creator of basketball, used a soccer ball as the first basketball. The game of soccer was originally played with an inflated animal bladder that was surrounded with leather (Leibs 67). Just as in every sport, as time evolves, so do the materials being played with. The materials begin becoming more durable, controllable, and affordable. During the Renaissance period, many sports were evolved and took a turn for the better. Although many sports were introduced during the Renaissance period; football, lawn bowling, and tennis were the three main sports that influenced today’s time period the most.
Through participation in skill learning and game play during the volleyball unit, this report will observe and analyse the characteristics of skilled performer through feedback in technique that was given by my fellow class mates and the coach and develop and participate in training activities that could correct these weaknesses.
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.
On the contrary, if the balls are smaller, these balls produce a much weaker bounce.
Exercising with BOSU can provide support, opposition, protecting and motivation to magnify the effect for this growing number of exercisers. It will help these exercisers to build practical strength, face the concern of tumbling down, practice different methods of getting up and getting down, train mental tasks and finally make all every day movements comfortable to do. Training program for seniors which made use of the BOSU ball helped improve their posture and balance, thereby reducing the risk of their accidental falling. A BOSU ball is also helpful in recovering from injuries and relieving back
