Physics
Answer
The law of inertia or Newton’s first law of motion states that —
If a body is in a state of rest, it will remain in the state of rest and if it is in the state of motion, it will remain moving in the same direction with the same speed unless an external force is applied on it.
It implies that,
(i) if a body is at rest, it remains at rest unless a force is applied on it.
(ii) If a body is moving, it will continue to move with the same speed in the same direction unless a force is applied on it.
