Newtons 3rd law

Kyle Tucker ran and jumped on his surfboard in shallow water.

After he jumped on the board, what happened?

• Kyle's motion made him and the board move forward.

• Kyle's motion made only the board move forward.

• Kyle's motion made him and the board stop moving.

• Kyle's motion made only him move forward.

Yoda was driving his blue car but didn't notice the car sitting in front of him.

What happened after he hit the parked red car?

• The energy of the moving car will make it bounce off of the parked red car.

• The energy of both cars will cause them to be unchanged.

• The blue car will gain energy from the red car and speed up in the same direction

• The energy will send both cars backwards from the direction the blue car was traveling

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

How does the magnitude of the force exerted by the top box on the bottom box compare with the magnitude of the force exerted by the bottom box on the top box for each of the stacks?

• The two magnitudes are always equal in each of the stacks.

• The two magnitudes are always different in each of the stacks.

• The two magnitudes are equal when the boxes have equal mass and different when the boxes have different masses

• The two magnitudes are equal when the elevator is moving at constant speed and different when it is accelerating.
