An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Friction oppose relative motion. In its absence, a moving object will not stop.
In simple terms, If there is no friction then the object won't stop nd keep moving.
Answers & Comments
Answer: If there was no friction, moving objects would continue to move even if there is no force acting on it.
Explanation: It does not require a force to keep an object moving, but to stop an object that is already moving, a frictional force is required.
