# Newton's Laws - Mission NL12 Detailed Help

 In baseball, the baseball strikes the catcher's mitt and is stopped due to the marvels of Newton's third law. Identify the two letters corresponding to the action-reaction FORCE pairs which are responsible for the stopping of the baseball.
 Newton's Third Law: For every action there is an equal and opposite reaction.
 Action-reaction force pairs help explain why objects start up and slow down. In the case of a baseball, there is the interaction between the catcher's mitt and the ball. Like any interaction, it is a mutual interaction between two objects that results in equal forces on both objects directed in opposite directions.   To answer this question correctly, look for the pair of action-reaction interactions between catcher's mitt and ball. The action and reaction statements should involve these same two objects. And the interactions should be directed in opposite directions.
