# Explain non-uniform circular motion with examples.

## Question:

Explain non-uniform circular motion with examples.

## Uniform motion:

In a uniform circular motion, the speed is constant, as is the centripetal force is also constant.

Nonuniform motion:

The magnitude of the angular velocity changes over time, so centripetal force is not constant.
