These simulations illustrate the conservation of energy and the change of energy from one form to another. The objects that are simulated include: a dropped ball, a pendulum, a spring, and a roller coaster. A final simulation illustrates how a bounced ball loses its kinetic energy and gravitational energy to heat.
In each simulation, the variables, like the height for the gravitational potential energy, can be measured or are given. In the included worksheet, students be asked to calculate out the energy values to confirm the conservation of energy.
The worksheet assumes that you have already started with the concept of work and will ask students to derive the equations for KE, GPE, and SPE from W=Fd.
There are two separate software simulations. The first can show the calculated energies and can be used for review before or after students work on the worksheet. The second does not show the calculated energies and is designed to be used by the students while completing the worksheet.
There is also a simulation showing graphically how the SPE changes as a block on a spring moves back and forth.
