Newton's Laws of Motion
Newton's First Law
An object at rest tends to stay at rest, or if it is in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an outside force.
Newton's Second Law
A body will accelerate with acceleration proportional to the force and inversely proportional to the mass. F=MA
Newton's Third Law
Every action has an equal and opposite reaction.
