A ball rolls down from the top of a grassy hill, reaches the bottom of the hill, continues to roll, and then starts to slow down and comes to a stop. What forces caused this ball's motion?

• Frictional force caused the ball to roll down the hill, but air resistance caused the ball to slow down and stop.

• Magnetic force caused the ball to roll down the hill, but gravity caused the ball to slow down and stop.

• The force of the hill caused the ball to roll down it, but gravity caused the ball to slow down and stop.

• Gravity caused the ball to roll down the hill, but frictional force caused the ball to slow down and stop.
