Ball Bearing Lab

Ball Bearing Lab

Procedure:

1. Put the ramp against something and make it as tall as 20 cm, 40 cm and Vertical. 2. Place the ball bearing at the top of the ramp.3. Release the ball 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.

Observation:

The less the height of the slope is, the faster it will be which means the fastest would be 20 cm and the lowest will be Vertical.

Analysis:

1. Describe how the ball rolls off the ramp at each height—discuss the effect of bouncing or other factors.
ANSWER The Fastest speed is 20 cm height and the slowest is vertical. That's mean height has a reverse variation for speed. Also, height has a direct variation with bouncing and bouncing make the ball lost some energy too.

2. Discuss what is the fastest speed reached and any factors that could improve this.
ANSWER The fastest speed is 1.6 meter per second. We can improve this by decrease the height of the slope.

3. Does the ball travel in a straight line, why or why not?
ANSWER No because force that force the ball in every direction is not equal.
Team work!

Listening to the instruction.
