  • 20. Ken rolled a ball along the floor. After a while, the ball slowed down and stopped. Which of these best explains why the ball did not keep rolling?

  • All the forces on the ball were equal.

  • The force of friction acts against the ball’s motion.

  • There were no forces acting on the ball as it rolled.

  • The force of gravity pushes the ball away from the floor.
