The following are three types of inertia

1. Inertia of Rest: When resistance is provided by the body to remain in a state of rest unless the external force is working through it.

2. Inertia of Direction: When resistance is provided by the body to continue to move in the same direction without the external force acting on it.

3. Inertia of Motion: When resistance is provided by the body to continue to be in the same direction without the external force acting on it.
