The elastic energy principle of rubber bands is used in the wind-powered car. When the rubber band contracts, it generates elastic potential energy. When the rubber band is released, the elastic potential energy is converted into kinetic energy of the propeller, which makes the propeller rotate. The rotation of the propeller generates a reaction force from the air, thereby pushing the wind-powered car to slide.
