1)Inertia of rest: this is the resistance offered by the body to remain in rest unless an external force is not applied on the body.
eg.: i)i a carpet is beaten with a stick then the dust particles due to inertia of rest tends to remain in rest while the fibers of carpet becomes in motion.
ii)With​​​With a quick pull, a table cloth can be removed from a dining table without disturbing dishes on it due to the Inertia of rest. The inertia of rest of the dishes keeps them where they are.
