Transcript Energy - Net Start Class

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!!!!
