Question

How to explain newton's first law of motion

Answer 1

First law: In an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a net force.

Answer 2

Newton's First Law of Motion states that an object at rest tends to stay at rest and that an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
