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 the ball's motion?

• Friction caused it to roll down the hill, air resistance caused the ball to slow down and stop.
• Magnetic force caused the ball to roll down the hill but gravity caused it 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 friction caused the ball to slow down and stop.
