• The action and reaction forces are equal in magnitude and opposite direction.

• For every action force acting on an object, there is a reaction force acting on a different object.

• The sum of the forces acting on an object is equal to its mass times its acceleration.

Newton's Third Law of Motion is ...

• The sum of the forces acting on an object is equal to its mass times its acceleration.

• For every action force acting on an object, there is a reaction force acting on a different object.
