Name the different kinds of inertia an object can possess. Give an example of each.

उत्तर
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.
