Newton's laws of motion

The three laws of motion as compiled by Sir Isaac Newton:
First law - An object will stay at rest or continue at a constant velocity unless acted upon by an external unbalanced force. (Law of inertia)

Second law - The rate of change of momentum of a body is proportional to the resultant force acting on the body and is in the same direction. (Law of acceleration)

Third law - For every action, there is an equal and opposite reaction. (Law of reciprocal actions)

Physics is fun, once you get the hang of it.
