Description

Used to explain the conservation of mechanical energy and its conversion from one form to another. After the wheel is being rotated by the hand to roll the supporting cords to the top and then released, its potential energy gets converted to kinetic energy as it falls. After the bottom position is reached by the wheel, The kinetic energy gets converted back to potential energy as it rolls the cords up again. This process continues until all the energy is lost to friction. Includes activity guide.
