Solution
An object possesses two kinds of inertia, the inertia of rest and inertia of motion. A book lying on a table will remain placed at the table unless it is displaced by some external force. This is an example of inertia of rest.
A ball rolling on the ground will continue to roll unless the external force, the force of friction between the ball and the ground stops it.
