Air Pressure Of A Soccer Ball

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

For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder.

The aim of this report is to analyse my overhand volleyball serve from a biomechanical perspective and compare it to an elite athlete’s overhand volleyball serve. Biomechanics is the sport science field that applies the laws of mechanics and physics to human performance, in order to gain a greater understanding of performance in athletic events through modelling, simulation and measurement. It is also necessary to have a good understanding of the application of physics to sport. In volleyball the applications of summation of forces, projectile motion and balance and stability have a major influence on the success and accuracy of an overhead serve.

This soccer science fair project serves to acquaint students with basic information on how the amount of air in a soccer ball can affect the distance it travels when kicked with a consistent force. The greater the air pressure in the ball, the farther it will travel when a force is applied. In the process of conducting the research, the student will learn that atmospheric pressure may also affect how far the ball will travel. The student will learn about the relationship between air pressure and friction: the lower the friction, the farther the ball will go. The student will learn about concepts like air pressure, gravitational force, compression and expansion of air molecules, potential energy and kinetic energy. This science fair experiment

Incorrect technique can lead to poor performance but can be improved by correcting biomechanics such as balance, stability and centre of gravity. Performance can also be increases by adding spin to the ball. Athlete spend years trying to improve their performance by perfecting correct technique

I chose to investigate the soccer ball because since a young boy soccer has been my obsession and favourite hobby. I also chose it since I was very intrigued on how to apply scientific methodology to enhance my kicking ability.

In the United States of America 64% of the population watch football, but no one ever thinks of the physics involved. One common misconception is people think that quickness and speed can go hand in hand, but in fact quickness and speed are 2 different things. Quickness is acceleration and that is the speed in comparison to direction. However speed is the rate of change per second. “Galileo was the first scientist to make a comprehensive study of kinematics” (pg. 27). How does physics relate to football? Football has many examples of how physics can be used to better understand it. another example is acceleration, even more acceleration versus speed. Speed velocity and acceleration are

Based on the surface a basketball collides with, it does affect the height of the bounce of the basketball when dropped from one meter. In this case the surfaces that we investigated were a table top, the classroom floor, grass, pavement, and dirt. The average height of bounces for each of the surfaces that were tested was the table top with 60 cm, the classroom floor with 66.4 cm, the grass with 63 cm, the pavement with 68.8 cm, and the dirt with 71.4 cm. The type of surface the basketball was bounced on affected its height because when a basketball bounces off of a surface, some of its energy is absorbed by that surface. More energy is absorbed by some surfaces more than others. A soft surface, such as the table top, absorbs more energy when

Soccer has become an important part of the culture in America. Recently, the Women’s National Soccer team even won one of the biggest honors possible, the World Cup. People play and watch soccer games all of the time and yet few people actually realize the physics that are involved in almost everything that they see or do. While there are multiple ways that physics is used in a soccer game, this paper explores three parts and the physics that are involved in each one. The three parts that are going to be discussed are passing a soccer ball, heading a soccer ball, and throwing the soccer ball back into play.

A soccer player takes a free kick about 30 meters from his opponent’s goal, hits the ball far to the right, and then almost magically the ball curves to the left and enters the top right-hand corner of the goal. Not only does this amaze fans across the globe but leaves many wondering how this is even possible. Players’ practice this kick all the time and know intuitively how to curve the ball by hitting it at a particular velocity, spin, and angle. However many probably don’t know the physics behind it. Understanding the physics of motion, the physics of friction, and even aerodynamics can help someone become a much better soccer player. Physics explain why a soccer ball curves, why the ball bounces and how high it bounces; as well as how

The strong trend (all R^2 values above 0.9) shown in Graph 2 (see 2.3 Results) of how air pressure affects the bounce height of the ball is: as the air pressure of a ball increases, the coefficient of restitution increases at a decreasing rate thus forming a logarithm relationship. Unfortunately, the logarithm relationship cannot be confirmed and proved as the data has not been linearised due to the lack of mathematical knowledge and an insufficient number of tests to fully determine the trend. Although, it is also likely that a more complex relationship may be involved between the air pressure and bounce height. A possible asymptotic relationship can be considered rather than a logarithmic

The subject stood on the mat, with legs shoulder width apart and jumped vertically upwards, as high as they could. The mat measured the time between the subject’s feet leaving the mat and landing again. The results were shown on a hand held device that recorded the subject’s air time in order to determine the height at which the subject jumped (Leard et al., 2007). The subject repeated the jump three times and the highest jump was

Most people think the size of the player will affect the outcome of the ball. This is not necessarily true. The mass of a professional soccer ball is about m=0.4 kg. The velocity of the ball equals the velocity of the leg multiplied by the fraction of the mass of the leg over the total mass of the leg and the ball, multiplied by 1 +

The aim of the investigation was to determine the bounce efficiency of a tennis ball at varying heights and it was hypothesised that as the drop height was increased, so too will the bounce height due to the extra gravitational potential energy being added with an increase of drop height. The findings indicated subtle changes occur in the bounce efficiency of the tennis ball from 91%, but with an overall decline in the chosen linear trend line. The results of the experiment support the hypothesis that as drop height increases, so too will the bounce height due to an increase in gravitational potential energy, however the bounce efficiency remained relatively

The purpose of this experiment was to investigate the correlation between a ball’s gravitational potential energy to it’s return mechanical energy. The major finding of this experiment was the fact that the return mechanical energy was increased as the gravitational potential energy increased. The hypothesis that the greater the weight of the ball would increase the return mechanical energy largely, was proved incorrectly by the data mostly. The average of the golf ball at 100cm drop was indeed greater than any other ball, except the return mechanical energy of the golf ball in the other drop heights at 75cm, 50cm, and 25cm, were less than another ball. In all those drop heights, the return mechanical energy was greater in a ping pong ball,
