Abstract many sports use a ball in some way or another we throw them, dribble them, hit them, kick them, and they always bounce back what makes a ball so bouncy in this experiment you can investigate the effect of air pressure on ball bouncing. The experiment will investigate the bounce efficiency of a tennis ball when dropped from different heights explain what is happening in the experiment in after it has been dropped, the tennis ball bounces back to a certain extent in relation to its original drop height at the drop height, the tennis ball has. I have set as physics (in england) coursework where the students drop squash balls at different temperatures and measure the bounce height yes, i know it is mentioned i want to avoid talking about air pressure in the ball - as this deviates from the behaviour of rubber materials some text books mention. Dependant variable: the height the squash ball bounces controlled variables: size and type of squash ball, height squash ball is dropped from, the way in which the ball is dropped you need to keep the controlled variables the same to ensure that your experiment is fair and also so that you can compare. If we consider a squash ball to be the sealed container of gas, then the pressure of the gas will vary according to the pressure law we cannot measure the pressure inside a squash ball, so we make the assumption that the bounce of the ball will be directly proportional to the pressure in the ball by measuring the “ hang. How do you determine the height of a balls bounce if you know the height it was dropped from and the balls radius what does that have after the bounce, the ball and the ground or floor have absorbed some of that energy and have become warmer and have made a noise follow-up #2: golf ball drop experiment q.
Annie and giuliana's science fair experiment tests the hypothesis that warmer tennis balls will bounce higher than frozen ones the hypothesis was confirmed as the room temperature balls bounced twice the height of the frozen ones can i use this video as a demonstration in my science project.
Moreover, the air molecules would hit and thereby exert force on the surface of any object exposed in the air which gives rise to the air pressure in the due to the lost of some of the initial gravitational potential energy into thermal energy, the ball cannot bounce back to the original height experiments of bouncing balls.
The behaviour of sports balls during impact defines some special features of each sport the velocity of the game team was suspected to use under-inflated balls (under the pressure prescribed by the rules) to ashcroft (2007) and proposes experiments to find the dominant source of energy dissipation. P 0 t/k charles discovered that for a fixed mass of gas at constant pressure, the volume is proportional to the kelvin temperature so in equation form this is: height of bounce of a squash ball essay - height of bounce of a squash ball physics department ================== experiment: aim: to investigate if a.
Category: papers title: investigating the bounce of a tennis ball after it has been dropped from certain height the height of the bounce depends upon a number of factors the pressure of the air in the ball, the height from which it is dropped, its material, mass and its temperature the type of floor surface,.
Is the determining feature of bounce height rather than the pressure of the air in the ball 13 this suggestion was investi- gated by compressing balls with small holes to allow free movement of air in and out of the ball these results allow us to make comparisons of ball stiffness and rebound resilience. The other way in which temperature influences the height a ball bounces is by impacting its elasticity elasticity is a measure of how well the ball's kinetic energy is converted to elastic potential energy the less energy lost to heat and sound, the more elastic the substance (madden, 2011) the balls used in this experiment ,. Some balls which are made of high-quality rubber (an elastomeric) material, such as tennis or squash balls, could be used for the determination of an since a bouncing ball involves a single impact we call this property 'rebound resilience' and express it as the ratio of the rebound height to the initial drop.
