Energy cannot be created or destroyed,but we can…..
transform it into other sorts of energy.
Law of Conservation of Energy: a principle in physics which states that energy cannot be created or destroyed.
Energy Transformation: the change of energy from one form to another.
The original source of energy – even for all other sources of energy is…
the SUN!!!!
