Energy is the ability to do WORK
Work is a Force over a Distance
So energy is the ability to MAKE SOMETHING
MOVE!
Energy is measured in CALORIES or JOULES

The 8 Types of Energy:
2. Potential Energy: Stored Energy
Comes in 2 types:
Elastic:
Energy stored by stretching.

The 8 Types of Energy:
Flammable: If something can burn it is because
it releases the energy along with diatomic molecules
of oxygen.

The 8 Types of Energy:
pH: When acids or bases react with things it is
from the energy of their H+ and OH- ions breaking
the bonds of other molecules.

The 8 Types of Energy:
Electrical Energy: The energy from the
movement of electrons.
In static electricity, electrons build up and then
all move at once as a discharge.

In CURRENT electricity, electrons flow through
closed circuits.

The Law of Conservation of Energy
Energy cannot be created or destroyed.
You can't make blue energy out of nothing!

The Law of Conservation of Energy
The amount of energy in any chemical reaction
is constant. So the energy in the
delicious Tex-Mex meal could
Be converted into all the body
heat, running, thinking, and
bodily functions used during
a normal day of running and
screaming.

The Law of Conservation of Energy
Energy in any form can be converted to any
other form through different processes.

The Law of Conservation of Energy
Any energy transformation produces some
thermal energy. The less thermal energy produced,
the more efficient the energy transformation.

The Law of Conservation of Energy
Nuclear changes can convert some matter into
energy and vise versa.
