Potential Energy & Kinetic Energy
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…
• can NEVER be created nor be destroyed!
• can only be STORED or TRANSFERRED.
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 that 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 to compression or expansion of an elastic object.
Notice the ball compressingand expanding
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.
