Transcript of Bouncy Ball Lab Report

Hypothesis
As drop height increases, bounce height will increase because the ball will have a higher velocity.
Data Collection and Results
Data Analysis/Conclusions
From our data, we can conclude that as the drop height increases by 1 centimeter, the bounce height increases by 0.65 centimeters. (on average)
We noted that most other groups had a very similar rate.
This shows that as the drop height increases, the bounce height increases. This confirms our hypothesis.
A possible source of error in our experiment is the angle at which the ball was dropped. In future experiments, an autonomous dropper is recommended.
Real World Question #1
Would you be able to play ping pong with your ball?
I believe that we would be able to play ping pong with our ball because it was exactly like a regular ping pong ball. It was small and very hollow which meant that it had a pretty good bounce.

Experimental Design:Materials
Meter Sticks
Tape
Ping Pong Ball
Slow motion camera
Real World Questions #2
If the material of your ball changed, how would it affect your balls bounce?
If the material of the ball changed, it would affect our balls bounce because the mass would be changed which hugely affects the bounce of the ball, the ball will get distorted in a different way when it hits the ground (elasticity) which also affects the bounce of the ball, and the material can be hollow (like the ball we already had), or it can be very thick like other balls we saw throughout this experiment in our class.

Experimental Design: Procedure
1. Before you begin your experiment, tape 2 meter sticks on the wall for measuring drop height and bounce height.
2. Use a slow motion camera to record each trial.
3. Drop a ping pong ball onto a tile floor from 50 cm, measuring in front of the meter sticks from the bottom of the ball.
4. Review the footage to measure the bounce height
5. Record the highest bounce
6. Repeat steps 3-5 for two more trials
7. Repeat steps 3-6 for drop heights of 100 cm, 150 cm, and 200 cm

The data was collected by reviewing the slow-motion footage and recording the highest bounce height.
