Newton's Laws of Motion

Newton's First Law

(Law of inertia) A object at rest remains at rest and a object in motion continues to move at a constant velocity unless acted upon by an external force.

Newton's Second Law

Force causes an object or mass to accelerate. The greater the mass to be accelerated, the greater the force required to move the mass.

Force is mass times acceleration.

Newton's Third Law

For every action there is an equal and opposite re-action.
