What is ENERGY?
• Energy is the ability to do work.
• Everything that happens in the world uses energy!
• Most of the time we can’t see energy, but it is
everywhere around us!

Energy…
• is NEVER created or destroyed!
• can only be STORED or TRANFERRED.

Batteries store energy!
This car
uses a
lot of
energy
We get
our
energy
from
FOOD!
Even this
sleeping
puppy is
using
stored
energy.

Remember:
ALL matter is made up
of particles.
The particles NEVER
stop moving.

How is all energy divided?

Potential Energy is…
• The energy stored in an object.
• "Potential" simply means the energy has the
ability to do something useful later on.

What is Gravitational Potential
Energy?
o Potential energy
due to an object’s
position
o P.E. = mass x
height x gravity
Don’t look down,
Rover!
Good boy!

What is Elastic Potential Energy?
o Potential energy due compression or
expansion of an elastic object.

What is Chemical Potential Energy?
o Potential energy
stored within the
chemical bonds of
an object

Kinetic Energy Is…
• The energy of a moving object.
• "Kinetic" means movement!
• When stored energy is being used up, it is
making things move or happen.
