The wind turbines in the image above generate electrical energy, but they do not create energy. Where does the energy harnessed by wind turbines come from?

What property of light energy allows lighthouses to signal and warn ships?

Amy is at basketball practice. She is about to shoot a free throw. When she releases the ball ….

Clyde and Marilyn are riding a roller coaster. During which section(s) of the track is their kinetic energy converted to potential energy?

Skateboarders use a structure called a half-pipe, like the one shown below, to do some impressive moves. Neglecting friction, at which point will the skateboarder's kinetic energy be greatest?

Robin is swinging back and forth from a trapeze. In which of the following situations is his kinetic energy being transformed into potential energy?

Vincent is playing pool. When he hits the white ball with the cue stick, the ball gains kinetic energy, which is the energy of motion. But once the white ball hits the first ball in the rack, the other balls on the table scatter, and the white ball comes to a stop. If the white ball has no kinetic energy when it is stopped, where did all of its energy go? Assume there is no friction in this system.
