Physics for IGCSE & O level - Forces And Motion (Section 8 - No. 18)

It will accelerate.
It will decelerate.
It will move at a constant velocity or remain at rest.
It will stop immediately.
Explicaţie
Newton's first law of motion dictates that the object will either remain at rest or continue moving at a constant velocity.
