QUESTIONS and EXERCISES

1. Check the frame time and use free fall equations to determine the height of each drop.

2. Find the % return for each drop with the class data and with the values found in # 1.

3. How far did the ball travel?

4. How long in seconds would you see some motion in the ball?

5. Work with different % return values to see if you agree with the claim.

6. Write a short report of the project and include some comments about the camara angle and other errors that may influence your information and conclusions.

7. Turn in the report with your calculation page, data page and graphs or diagrams attached.
