This site explains and gives examples of elastic potential energy and how to calculate it.

Kids learn about potential energy in the science of physics. The energy of position and state can be calculated using mass, gravity, and height. The standard unit is the joule. How it is different from kinetic energy.

This comprehensive lesson teaches all about energy, including the different forms, the periodic table, history of human energy use and production, and energy units. It contains an interactive energy calculator, games and activities, and...
