When you rub your hands together, you are converting mechanical energy into heat energy. Chemical energy is the energy released when atoms bond together. The fuel in a rocket engine has stored chemical energy. When the fuel is ignited the fuel's stored chemical energy becomes heat energy and mechanical energy. When you throw a ball you are also using stored chemical energy and turning it into mechanical energy.
Nuclear energy is the energy produced in the nucleus of an atom.
When the nucleus of an atom splits, nuclear energy is produced in the form of heat energy and light energy. Power lines carry electromagnetic energy in the form of electricity into your home to power your lights and appliances. Visit the Utah State 8th Grade Integrated Science Core Curriculum Page .
