Battery powered Lego crane lifting a weight. An electric motor,powered by three batteries (cells),drives a wheel and pulley to lift a weight attached to a string. This demonstrates energy conversion (transformation). Chemical energy is converted by the batteries (top left) into electrical energy. The motor then converts the electrical energy into kinetic energy in the wheel (centre),pulley (top right) and string,and raises the weight (bottom right) | |
