Moment of inertia of any body defines its ability to resist angular acceleration. The moment of inertia is varied by mass of the particle in a body and its distance from the axis of rotation.
This experiment shows a simple ramp where four objects of the different profile (hence different moment of inertia) were left to roll without the variable of slippage.
The objects are, from back to front:
- A hollow spherical shell (red)
- A solid ball (orange)
- A ring (green)
- A solid cylinder (blue)
