Questions

1. What relationship did you find in Part I between the acceleration of the ball and the angle of the wooden board? Explain this in terms of the gravitational force.

 

 

2. In Part II, did all of the balls reach the ground in approximately the same time? Were their acceleration values comparable? Explain.

 

 

3. How did the results for the Styrofoam ball compare to the others? Can you account for this difference?
