Notes
There are three major
types of energy.
•Potential energy
•Kinetic energy
•Mechanical energy
Potential Energy: the energy of
something NOT in motion. This item
has the energy stored inside
of it. It is not using the energy right
now.
Potential Energy
When the ball is NOT moving,
it is storing its energy.
Usually an object has potential
energy because of where it is or
because of its condition.
MOST potential energy

Kinetic Energy: the energy of
moving. If it is moving, it is using
kinetic energy.
Types of kinetic energy:
•
•
•
•
•
•
Chemical energy
Electric energy
Light energy
Sound energy
Heat (thermal) energy
Mechanical energy
Kinetic Energy
When the ball is MOVING, it is
using energy.
Kinetic Energy
When you are moving, you
are using energy.
Kinetic Energy
When fish are moving, they
are using energy.
Are these fish using kinetic energy?
Why not?
Which are using kinetic energy and
which are using potential energy ?
Mechanical Energy
Mechanical Energy: the energy of something in
motion and doing work. Something must be
accomplished to be considered work.
