![]() Lab 9: Bouncing Ball Consider the following setup of a bouncing ball (ignore drag for the purpose of this lab): descending ascending YA= 1.20 m Yo= 0. Show your calculation for the impulse delivered by the ground during the bounce, Show your calculation for how fast the ball was going right after the bounce (right as it left the ground). is the initial velocity and g is the acceleration due to gravity. ball behave the same way if you tried to dribble on a football or soccer field Plan and conduct your own experiment to compare the basketballs bounce. Show your calculation for how fast the ball was going right before it hit the ground. will record the position of a bouncing ball over time and calculate the resulting. Show your calculations for how much thermal energy was lost during the bounce. Show your calculations for the potential energy at point A and at point G. Outline the energy transformation as the ball goes from point A to point G. Draw a FBD for the ball (a) before the bounce (b) during the bounce (c) after the bounce. Pictorial representation (sketch the setup) 3. In this program you will be able to change the type of ball, the height from which it is dropped and the acceleration due to gravity in the region of the. Pictorial representation (sketch the setup)įor the write-up: 1. In order to collect all the data for this experiment. Determine the height of the drop and the bounce by measuring from the bottom of the ball. In the animation, both balls DROP to the floor from frames 1 to. Controlled variables include, but are not limited to, the mass of the tennis ball and gravity. In groups of 4, divide the activities so that 1) one student drops the ball, 2) one student watches the bounce and estimates the height to which it bounces, 3) one student measures the height of the bounce,and 4) one student records the data. © 2013 American Association of Physics Teachers.Transcribed image text: Consider the following setup of a bouncing ball (ignore drag for the purpose of this lab): For the write-up: 1. We did the Flash bouncing ball example shown here in StudioIT 1 computer hands-on lab classes.Vogt, “ Smartphones as experimental tools: Different methods to determine the gravitational acceleration in classroom physics by using everyday devices,” Eur. Thereby we measure the time between two impacts, i.e., Δ t = 2 t H. The kinetic energies E kin 1 and E kin 2 between two subsequent impacts behave like the squares of the impact velocities, and the rise and fall times t H of the ball are given with t H = v 0 g. Astronauts experienced less gravity on the Moon, so dropping a ball on the. ![]() Alternatively, a commercial measuring system or a free sound editor (e.g., Audacity) can be used to make the acoustic recordings. They simulate the experiment by dropping high- and regular-bounce balls from. ![]() The Oscilloscope app can be bought in the Apple Store at the following link for $19.99: /us/app/oscilloscope/id388636804.

This changes the direction of the ball and sends the tennis ball bouncing.
