6.9: Force, motion, and energy. The student knows that the Law of Conservation of Energy states that energy can neither be created nor destroyed, it just changes form. The student is expected to:

6.9c: demonstrate energy transformations such as energy in a flashlight battery changes from chemical energy to electrical energy to light energy.

Chemical Energy - Energy that is released during a chemical reaction or change

Electrical Energy - Energy in the form of electricity

Light Energy - Also known as Radiant Energy, this energy in the form of electromagnetic waves

Law of Conservation of Energy - This states that energy can neither be created nor destroyed. It can however be transferred to another form.

Mechanical Energy - Energy that an object such as a machine has because of its movement or position
