Question

According to Newton’s first law of motion, what will an object in motion do when no external force acts on it?

Answer 1

According to Newton’s first law, the object will either continue at a constant velocity/speed with an acceleration of 0 or remain at rest.

Answer 2

Answer:

It remains in motion.

Explanation:

According to the Newton's first law of motion, if a body is in motion it remains in motion or if a body is at rest it remains at rest until and unless an external force is not applied on the body.

So, here the object is in motion and no external force is applied, so remains in motion as the same.
