1K10.50 - Rolling a Disc Uphill

Code Number:
1K10.50
Demo Title:
Rolling a Disc Uphill
Condition:
Excellent
Principle:
Centers of Mass, Torque
Area of Study:
Mechanics
Equipment:
Hydraulic Table/Ramp, Disks and Sphere with offset center of mass.
Procedure:

Incline the ramp to the desired angle.  Place the disk or sphere on the ramp and turn them so that the mass is toward the top.  Let go and they should roll a short way up the ramp.
