Speed lab ball

I observe that if the ball fall from highest height it can travel with higher meters.Ex. if we drop ball from 20 cm it will travel shorter than 40 cm and 60 cm.Because if we drop ball in the shortest height it will have less push than 40 cm and 60 cm.


1.Describe how the ball rolls off the ramp at each height—discuss the effect of bouncing or other factors.

Ans When the ball rolls off the ramp at 80 cm height it will bouncing higher than 60 cm or 40 cm.Because if the ball smash with ground with high force it will reflect with high force too.So if it smash with high force it can be bounce in high distance.Another factors is if we drop the ball in the high height it can travel longer than short because it has push force.

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

Ans Fastest speed reached that we doing the lab is 8.93 meters.The factor that could improve this is the ground because every ground have different friction force so the ball can be short and can go long distance.

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

Ans No,because when the ball travel maybe it will have wind and some ground it not flat.
