Potential and Kinetic
Energy
What is Energy?
• Anything that can cause a
change in matter.
Two Types of Energy:
1) Kinetic Energy
2) Potential Energy
Potential Energy
1. Potential Energy is stored
energy.
2. An object with potential
energy has the ability to
move or change.
Potential Energy
3. Potential energy depends
on an object’s position or
condition.
Example:
Examples:
Kinetic Energy
4. Kinetic Energy is the
energy of movement.
5. It depends on the mass
and speed of a moving
object.

Card Sort
• Determine if the situation
on each card is showing
potential energy or kinetic
energy.
PE and KE Lab!
• Follow all directions
carefully.
• Be sure you test each marble
position twice.
• Answer your conclusion
questions when your group
finishes.
Discussion
• When did the marble have the
most potential energy?
• When did the cup move the
farthest?
• What did this show you about
potential and kinetic energy?
How are Potential Energy
and Kinetic Energy related?
• Energy can be transferred from
potential to kinetic energy.
• If an object has more potential
energy to start, then it will have
more kinetic energy when it
starts moving.
Catalyst
• What is potential energy?
• What is kinetic energy?
• Give an example of each.
Homework
• On a blank sheet of paper,
draw two pictures of
situations showing potential
energy and two pictures of
situations showing kinetic
energy. Explain in words why
each situation shows that
type of energy.
Forms of Energy
Forms of Energy
1. All energy falls into two
categories:
• Potential: stored energy and
energy of position
• Kinetic: motion of waves,
electrons, atoms, molecules
and substances.
2. What Forms of
Energy Are There?
POTENTIAL
Chemical Energy
Nuclear Energy
Gravitational Energy
KINETIC
Radiant Energy
Electrical Energy
Mechanical
Sound
Thermal Energy
How will we ever
remember these?!
Just remember
the sentence:
Cam Newton
got really
excited making
stinky tacos.
Cam= Chemical
Newton= Nuclear
Got= Gravitational
Really= Radiant
Excited= Electrical
Making= Mechanical
Stinky= Sound
Tacos= Thermal
1. Cam=Chemical
• Energy
stored in the
bonds of
atoms and
molecules.
Example: Matches,
Digestion, batteries
2. Newton= Nuclear
• Energy stored
in the nucleus
of an atom.
The energy
that holds the
nucleus
Example: Breaking
together.
down Uranium
3. Got= Gravitational
• Energy of
place or
position.
Higher=more
gravitational
energy.
Example: two plants
4. Really= Radiant
• Electromagnetic
energy that
travels in waves
like light.
Example:
Visible Light
5. Excited= Electrical
• Movement
of
electrons.
Example: lamp,
computer
6. Making= Mechanical
• The
movement of
a substance
from one
place to
another.
Example: Riding a Motion.
bike
7. Stinky = Sound
• Movement
of energy
through
substances
in waves.
Example: bell
8. Tacos= Thermal
• The vibration
or movement
of atoms and
molecules.
Heat.
Example: stove
boiling water
