What does Newton's Third Law of motion state?

Newton's Third Law of motion states that if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object.

True or False? For every action, there is an equal but opposite reaction.

True. No matter what the action is, the reaction will be of equal strength in the opposite direction on the first object.

True or False? Action and reaction forces do not act in pairs.

False. The action forces causes the reaction force. You cannot have a reaction force without the action force occuring first.

Do action-reaction forces cancel each other out?

No. They act on different objects.

Are action-reaction forces balanced?

No. They act on different objects. Balanced forces are equal and opposite forces that act on the same object.

How do action-reaction forces explain how a gymnast can flip over a vaulting horse?

When the gymnast does a flip, he pushes down on the vaulting horse. The reaction force of the vaulting horse pushes him up to complete the flip.

True or False? Newton's Third Law explains how a rocket takes off into space.

True. The rocket exerts a force on the ground, and the ground exerts a force of equal strength on the rocket. Then, the rocket is pushed into space.

What is an example of an action-reaction force as you play outside?

The action force is the kid pushing on the ground. The reaction force is the ground pushing on the kid, which causes the kid to jump into the air.

True or False? You can always detect when paired forces are in action.

False: You cannot detect when paired forces are in action.
