Third Law of Motion
When one object exerts a force upon another object, the second object exerts an
equal and opposite force upon the first object.
Also known as:for every action there is an equal and opposite reaction;The
Third Law of Motion deals with balanced and unbalanced forces.
When the forces on an object are unbalanced, motion occurs.
The third law of motion explains the generation of thrust by a jet and rocket
engine and the motion of a college racing shell.
