Hang various masses from different springs and observe how kinetic, gravitational potential, elastic potential, and thermal energy are related, in this interactive resource adapted from the University of Colorado's Physics Education Technology project. A bar graph illustrates the conservation of energy by showing how the total energy of the system remains the same while the levels for the different forms of energy vary. Options allow you to choose the stiffness and amount of friction of a spring and see how different amounts of gravity affect the system.
