Physics for IGCSE & O level - Forces And Motion (Section 10 - No. 29)
If an object has zero net force acting on it, what will happen to its motion?
It will stop accelerating.
It will change direction.
It will experience a change in speed.
It will remain at rest.
Penjelasan
Zero net force means no acceleration. It will continue with the same speed and direction (Newton's First Law).
