What is Newton's law of motion

Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force

2nd - is a quantitative description of the changes that a force can produce on the motion of a body.

3rd - states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.

Newton's laws of motion relate an objects motion to the forces acting on it.
