ball bearing lab

1.         Describe how the ball rolls off the ramp at each height—discuss the effect of bouncing             or other factors.
            The more heigh that we roll the higher you get bouncing but less farther you get.

2.         Discuss what is the fastest speed reached and any factors that could improve this.

            The fastest speed is 1.6 cm./sec. I think the factors that will improve this is  the heigh of ruler and the ball type that it small or big or soft or heavy

3.         Does the ball travel in a straight line, why or why not?

             The ball not go straight line I think because of force that we roll in 4 side is not equal so the ball move not in the same direction and I think the wind effect to the ball so it get in different direction too.
