उत्तर
The three kinds of inertia are:
- Inertia of rest,
- Inertia of motion,
- Inertia of direction.
(1) Inertia of rest: The tendency of a body to continue in its state of rest, even when some external unbalanced force is applied to it, is called inertia of rest.
(2) Inertia of motion: The tendency of a body to continue in its state of motion, in a straight line, even when some external unbalanced force acts on it, is called inertia of motion.
(3) Inertia of direction: The tendency of a body by which it is unable to change its direction of motion, even when some external unbalanced force acts on it, is called inertia of direction.
