Inertia is the virtue of a body due to which it tries to retain its state. Inertia is of three types:
a.) Inertia of rest If a body is in rest, then it will remain in rest until an external force is applied on it.
b.) Inertia of Motion If a body is in motion, then it will remain in motion until an external force is applied on it.
c.) Inertia of Direction The tendency of a body to change by itself its direction of motion is called inertia of direction.
