Answer to Question 1

The brakes on a car: applying the brakes on a car slows it down through friction of the brake pads with the brake drums. The car slows down, losing kinetic energy, and the pads warm up, gaining thermal energy (try touching your wheels-but be careful because they can become very hot-after using your brakes for a long time, e.g.,going down a steep mountain road).
