The rubber band wind car utilizes the principle of elastic potential energy from a rubber band. As the rubber band contracts, it generates elastic potential energy; when released, this energy is converted into kinetic energy for the propeller, enabling it to rotate. The rotation of the propeller creates a counterforce on the vehicle, thereby propelling the wind car.
