Summary:

• For every action force there is an equal reaction force in the opposite direction.
• Action/reaction forces always occur in pairs.
• Action/reaction forces are simultaneous.
• The magnitudes of the action/reaction forces are equal but the resulting accelerations are usually not equal.
• By the Law of Acceleration, when objects or characters push apart the heavier one will accelerate less than the lighter one.
