Centripetal Force: How Central Forces Cause Objects to Spin or Turn

What are central forces and how do they make objects spin or turn?

Physics - Forces - Learning Points.

A centripetal force makes an object follow a circular path.

The moment of inertia is the resistance of an object when the speed of rotation is changed.

The axis of rotation is the line around which an object spins.

Centripetal force is used by satellites and fairground rides.
