Work, Energy, and Power


One recurring theme on the MCAT is that an object moving with both translational and rotational motion has two places to put kinetic energy. It possesses kinetic energy through its translational motion as well as through its rotational motion.

The MCAT writers seem to like problems involving the comparison of the rolling object versus the sliding object. The rolling object has more places for energy. How does this fact affect its speed down a plane?
