What is Energy?
The ability to do work or cause change.
Energy can NEVER be created or destroyed it can
only change forms. This is referred to as Law of
Conservation of Energy.
The Stored chemical energy you had for
breakfast is leaking out of the top of your head
as heat energy and being used as mechanical
kinetic energy (breathing).
What are the different types of
Energy?

Task 1
Write your scenario in your
notebook and be prepared to
demonstrate
Potential Energy
Potential energy is energy due to position or stored
energy. Potential energy is also called
gravitational potential energy. Potential energy
depends on Mass and postion.
• By stretching a rubber band, you give it potential energy.
• A vase on a shelf has stored potential energy.
• A football being held by a quarterback has potential
energy until it is thrown and it turns into kinetic energy.
Task 1: Create your own example of Potential
energy using the tennis ball. Be sure to explain
how your example represents Potential Energy.
Task 2
Write your scenario in your
notebook and be prepared to
demonstrate
Kinetic Energy
Kinetic energy is the energy of motion. Kinetic energy
is measured by how much is work done to put an
object in motion or to rest. Kinetic Energy depends
on Mass and Speed.
• A basketball player has kinetic energy. The movements
that she does show the energy that is being displayed
while she is moving.
• When you are running, walking, or jumping, your body is
exhibiting kinetic energy.
Task 2: Create your own example of Kinetic energy
using the tennis ball. Be sure to explain how your
example represents Kinetic Energy.
Task 3
Most objects have both Kinetic and Potential
Energy, where the object could be moving and
also storing energy at different times.
Task 3: Create scenario with the tennis ball, which
contains both Kinetic and Potential Energy.
