No work is done by gravity on a bowling ball that is resting or moving on a bowling alley because the force of gravity on the ball acts perpendicular to the surface. But on an incline, the force of gravity has a vector component parallel to the alley, as in B. How does this component account for (a) the acceleration of the ball and (b) the work done on the ball to change its kinetic energy?
