My 2nd Proficiency was applying Friction. I was trying to see if a ball would roll faster with more or less friction. So i put a sort of hard scrubbing material on one side of the ramp. i put a border in the middle and a plain wooden ramp on the other side.i rolled the same ball down each side 5 times.
Friction
1st- 1.1s
2nd-.6s
3rd-.6s
4th-.5s
5th-.7s
No Friction
1st-.5s
2nd-.8s
3rd-.6s
4th-.5s
5th-.4s
As you can see the rimes in alot of the places were very close but i believe the ball rolled better without alot of friction.
