Describe the term inertia with respect to motion.
Inertia:
It is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line unless we apply external force to change its state.
There are 3 types of inertia:
1. Inertia of rest
2. Inertia of direction
3. Inertia of motion
It is the property of the matter that causes it to resist changes in velocity.
The amount of inertia a body possesses is proportional to its mass.
