If net force is zero, what happens to motion?

Explanation:
When no unbalanced force acts on an object, its motion doesn't change. This follows Newton's first law: an object at rest stays at rest, and an object in motion keeps moving with constant velocity. The acceleration is zero, so both speed and direction remain the same unless some other force acts on it. If it started from rest, it stays at rest; if it’s moving, it continues to move in the same direction at the same speed. Therefore, the motion is described as moving with constant velocity.
