2. Potential Energy &
Kinetic Energy

3. 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!

4. Energy…
• can NEVER be created nor be destroyed!
• can only be STORED or TRANSFERRED.

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

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

7. How is all energy divided?

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

9. 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!

10. What is Elastic Potential Energy?
o Potential energy due to compression
or expansion of an elastic object.
Notice the ball compressing
and expanding

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

12. 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.
