Forms of energy
Energy exists in different forms.
Energy can be transferred from one form into another form.
When an object falls and gains speed, its gravatational potential energy decreases and its kinetic energy increases.
Some forms of energy include light, sound, kinetic, nuclear, electrical, gravatational potential, elastic potential and chemical.
Conservation of energy
Energy can be transformed from one form to another or transferred from one place to another.
Energy cannot be created or destroyed.
