how many laws of gravity did newton have
Newtonâs three laws of motion relate the forces acting on a body to its motion. The first is the law of inertia, it states that âevery object in motion will stay in motion until acted upon by an outside forceâ.The second is commonly stated as âforce equals mass times accelerationâ, or F = ma.The third and final law is commonly known as âto every action there is an equal and opposite reactionâ.he first is the law of inertia, it states that âevery object in motion will stay in motion until acted upon by an outside forceâ.
