Newton's First Law Of Motion
a body acted on by no net force moves with constant velocity(witch may be zero) and zero acceleration.

Newton's Secend Law Of Motion
If a net external force acts on a body,the body accelerates.The direction of acceleration is the same as the direction of the net force.The net force vector is equal to the mass of the body times the acceleration of the body.

Newton's Third Law Of Motion
If body A exerts a force on body B(an "action"),then body B exerts a force on body A(an "reaction").These two forces have the same magnitude but are opposite in direction.These two forces act on the different bodys.
