Solution

The options that involve energy transformations are:

  1. The motion of a roller coaster car as it travels around the track. This involves the transformation of potential energy (when the car is at the top of the track) into kinetic energy (when the car is moving).

  2. The Sun warming your skin on a hot summer day. This involves the transformation of the Sun's radiant energy into heat energy on your skin.

The use of an ice pack on an athlete's injured knee involves a transfer of thermal energy (from the warmer knee to the colder ice pack), but not a transformation of one type of energy into another.

A space craft moving through space at a constant velocity is not undergoing an energy transformation. Once it's in motion, no additional energy is required to keep it moving at a constant speed and direction.
