Inertia Investigation


 when i'm playing ball with my little brother in the park , the ball some times goes to this down hill but that down hill goes up after so therefor the ball goes back and front it never stops because there is no friction force.


Rolling with friction

 As you see this ball is stopping really quickly because there is fiction acting upon it. This means that something else is stopping the ball
