Investigating the Bouncing of a Ball.

... AS Level Physics Coursework - Investigating the Bouncing of a Ball Sarah Tayler In this investigation, a basketball was dropped from a certain height (2.24m), and its displacement was measured over a short period of time (approximately 5 seconds) using an ultrasound distance sensor which was fixed directly above. The basketball weighed 602g and had a diameter of 24.2 cm. The sampled data was recorded and used to plot various graphs. Table of Data (1,2): The recorded data is shown in the table, along with the displacement from the ground, velocity, acceleration, gravitational potential energy, kinetic energy and total energy. Although 99 samples were taken altogether, the last 8 have been discarded as the readings after that point became erratic. Displacement/Time graph (3): This graph shows the displacement of the basketball from the sensor. Each separate bounce is clear to see. Displacement/Time graph (4): This graph also shows displacement, but it shows the displacement from the ground, which is easier
