Energy: Potential vs. Kinetic

1
Energy Potential vs. Kinetic

• EQ How can you differentiate between potential
  and kinetic energy?

2
What is energy?

• Energy is the ability to cause change.
• There are 2 main types of energy Potential
  Kinetic

3

• Potential Energy is energy that is stored in an
  object but is not being used.

4

• An object that is not moving has potential
  energy.

5
Forms of Potential Energy

• Gravitational Potential Energy energy stored
  between the object and the earth
• Depends on the objects weight and height

6

• Elastic Potential Energy stored in objects
  that are compressed or stretched.

7

• Chemical Potential Energy stored in the
  chemical bonds between atoms.

8

• Kinetic energy is the energy of motion.

9

• An object that is in motion has kinetic energy.

10
What effects the Kinetic Energy?

• Speed
• Faster speed More Kinetic Energy
• Mass
• Greater mass More Kinetic Energy

Example

• Joe throws the football across the field.

Question 1

• Sam stands with his arms on his waist.

Potential Kinetic

Question 2

• The pencil sits on Katies desk.

Potential Kinetic

Question 3

• Sara holds the soccer ball in her hand.

Potential Kinetic
16
Question 4

• The bee flies through the air.

Potential Kinetic
17
Question 5

• The red flower blows in the wind.

Potential Kinetic

Question 6

• Carrie is skating in her new roller skates.

Potential Kinetic
19
Question 7

• The rocks sit in the middle of the road.

Potential Kinetic
20
Question 8

• The kite flies high in the sky.

Potential Kinetic
21

• Potential energy can change into kinetic energy

22
What is energy transformation?

• The change in energy from one form to another.

23
Law of Conservation of Energy

• Energy can be transformed from one form into
  another or transferred from one region to
  another, but energy cannot be created or
  destroyed.

24
Changing Potential Kinetic Energy

Explain what is happening in terms of potential
and kinetic energy.
