For an object sliding down a frictionless inclined plane, starting from rest, it is not hard to use energy considerations to show that it will move at a speed given by Vcm2 =
2gh, but according to Eq. (10.33), a ball (or other object) that is rolling down that plane will have less speed. Why is this true?
O Some of the energy goes into rotational motion, so there is less energy for motion of the center of mass
O Rolling causes friction, which slows the mass down
O The rolling object occasionally slips, which causes it to accelerate less
O The rolling object produces a reverse force that slows it down
