Newton's Third Law of Motion

When you hit a tennis ball with a racket...

• The ball exerts more force on the racket

• The ball and racket exert the same force on each other

• The racket exerts more force on the ball

• It depends on how hard you hit it

Two students with different masses are sitting in roll-y chairs. The lighter one uses his feet to push the other

• The lighter student will move faster because he has less mass

• The heavier student will move more because he is being pushed

• They will move with the same speed

• The heavier student shouldn't move at all

Newtons 3rd Law of Motion states:

• An object at rest will remain at rest unless acted upon by an outside force.

• For every action, there is an equal and opposite reaction

• The greater the mass of an object, the more force it will take to accelerate the object
