1. TYPES OF ENERGY Mechanical, Electromagnetic, Electrical,
Chemical, Nuclear and Thermal

2. What is Energy?
The ability to make things move – the ability to do WORK!!!
There are many machines that help us do work – can you name some?

3. TYPES OF ENERGY MECHANICAL CHEMICAL THERMAL ELECTRICAL NUCLEAR
Car, plane, wagon
THERMAL
Heat from moving molecules
Inside all matter; furnace
ELECTROMAGNETIC
Visible light, microwaves, radio waves
CHEMICAL
Batteries, matches, body cells
ELECTRICAL
Lightning, power lines
NUCLEAR
Nuclear power plants, atomic bomb, sun & stars

4. What is Mechanical Energy?
Energy due to a object’s motion (kinetic) or position (potential). Includes sound.
The bowling ball has mechanical energy.
When the ball strikes the pins, mechanical energy is transferred to the pins!

5. Examples of Mechanical Energy

6. What is Electromagnetic Energy?
Light energy
Includes energy from gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwave and radio bands

7. What is Electrical Energy?
Energy caused by the movement of electrons
Easily transported through power lines and converted into other forms of energy

8. What is Chemical Energy?
Energy that is available for release from chemical reactions.
The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.

9. Examples of Chemical Energy

10. What is Thermal Energy? Heat energy
The heat energy of an object determines how active its atoms are.
A hot object is one whose atoms and molecules are excited and show rapid movement.
A cooler object's molecules and atoms will show less movement.

11. Conservation of Energy
Energy is never created or destroyed – it is just transferred.
Energy transformations - when one type of energy transfers into another.
What type of transformation is occurring?
Electrical Mechanical

12. ELECTROMAGNETIC ENERGY
