1. Put the ramp against the seat of a chair. Place the ramp and chair so that the ramp points towards the hallway. Have your teammate on the other end of the hallway.
2. Place the ball bearing at the top of the ramp.
3. Lift the ramp 20 cm and release the ball bearing
4. Time how long it takes to travel 5 meters.
5. See how far it will go..
6. Repeat the experiment three times for each height then do 40 cm, 60 cm, and 80 cm.
Time to travel 5 meters
Observation: I Have observe that the higher the starting point of the ball is, the shorter the ball travel. But not all the time it is like that.
1. Describe how the ball rolls off the ramp at each height—discuss the effect of bouncing or other factors.
Ans; So when it start at 20 cm, the ball did't bounce much so it can go peaty far, the higher the ball is released the shorter the distance the ball travel, it is because the effect of bouncing. If it is a bouncing it would be a good effect on it but this is a plastic ball.
2. Discuss what is the fastest speed reached and any factors that could improve this.
Ans: The fastest speed is 3 second /300 cm
3. Does the ball travel in a straight line, why or why not?
Ans: No because the surface of the ground is not flat, and ball can roll anywhere although the surface of the ground is flat.
