ElectricalElectromagneticNuclear

Energy can be transferred, or

converted, from one form to

another!

Mechanical Energy

Energy associated with the motion of an object.

Rest + Motion

Law of Conservation of Energy

Energy can NOT be created or destroyed, only transformed from one form to another.

With every energy transformation some energy is always given off as heat energy.
