1. Describe how the ball rolls off the ramp at each height discuss the effect of bouncing or other factor
Ans: The ball rolls faster in the ramp, the effect of bouncing is the higher that bucket is the slower the ball will go

20 cm: 4.5 seconds for 5 meters
40 cm: 6.5 seconds for 5 meters
60 cm: 7 seconds for 5 meters
80 cm: 9 seconds for 5 meters

2.Discuss what is the fastest speed reached and any factors that could improve this
Ans: The fastest speed that the ball reached is when we roll the ball from the higher place to lower place. We can improve by using the longer bucket to make it have more gravity so the ball will be faster.

3.Does the ball travel in a straight line, why or why not?
Ans: In the lab the ball doesn't travel in the straight line and I think it is because the floor is not exactly straight or we don't roll the ball in straight line.
