1 Energy Forms and Conversion

2 ENERGY the ability to do work

3 WORK is done when you use a force to cause motion

4 WORK a force is moved through a distance

5 “CLUES” – Types of Energy
Kinetic Energy Gravitational Potential Energy Elastic Potential Energy Chemical Energy Thermal Energy Electrical Energy Nuclear Energy Radiant Energy

6 Kinetic Energy Energy of motion Examples: KE = ½*M*V2

7 Gravitational Potential Energy
Stored energy that depends on an object’s height Examples: GPE = M*g*H

8 Thermal Energy Energy of heat Examples:

9 Chemical Potential Energy
Stored energy in chemical bonds in compounds When released, energy can do work Examples:

10 Elastic Potential Energy
Stored energy of a compressed or stretched object Examples:

11 Electrical Energy Energy associated with electrical charges Examples:

12 Nuclear Energy Energy stored within nucleus of an atom Examples:

13 Radiant Energy Energy that travels through space in waves
Electromagnetic Spectrum Examples:

14 Sound Form of kinetic energy – movement of energy through
substances in the form of waves

15 Energy Conversion Cards
Front: Form of Energy Back: 3 examples On either side include: Picture of one of the examples

16 Practice on Your Own Energy Tracker: Jerome’s Story

17 To change from one form to another
Conversion To change from one form to another

18 Remember the 8 forms of energy…

19 A squirrel is walking along a telephone wire and then he falls off.

20 I stretch a rubber band, aim it at a student, and let it go.

21 An electric toaster is used to make toast.

22 A parked car begins to roll down the hill.

23 You jump up on a trampoline.

24 You plug in the microwave and turn it on.

25 A cloud is full of water. Eventually, raindrops fall from the sky.

26 You flip on a light switch and the lights come on.

27 Sunlight makes a flower grow.

28 You eat a Power Bar before running the mile.

29 A coal-burning power plant produces electricity.

30 Person is standing on a diving board.
They jump off.

31 A Roller Coaster goes up and down hills.

32 Gasoline in a car is burned and the car moves.

33 You light the coals in a grill, then cook a hotdog.

34 A nuclear reactor is used to make electricity.
I plug in a fan and turn it on.

35 I plug in an electric blender and turn it on.
Then I eat the delicious milkshake.

36 The sun causes carrots to grow.
A bunny eats the carrots and hops around.

37 A basketball rebounds off the rim and hits the ground.
