Two students sit on a seesaw in a way that makes it balance and not move. When a third person pushes down on one side, that side moves down. What caused the seesaw to move?

• The effect of gravity increased when one side was pushed down.

• The friction between the two sides decreased because of the push.

• The total force increased on the side that was pushed down.

• The push on one side of the seesaw decreased the force on the other side.

Which will happen to an object at rest if no other forces are acting on it?

• The object will stay at rest.

• The object will begin to move.

• The mass of the object will increase.

• The gravity on the object will increase.

What must be true for a baseball to be hit high into the air?

• The force striking the ball must be greater than the force of gravity.

• The force striking the ball must be less than the force of gravity.

• The force striking the ball must be equal to the force of gravity.

A student uses the same force to push a golf ball, a ping pong ball, a bowling ball, and a baseball. Which will move the fastest?

• The golf ball

• The ping pong ball
