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

2. Conduction
Conduction: The transfer of heat from one substance to another by direct contact
Examples:
-Touching a stove and being burned
-Ice cooling down your hand
-Boiling water by thrusting a red-hot piece of iron into it

3. Convection
Convection: Convection is the movement of molecules within fluids. It cannot take place in solids, since significant diffusion cannot take place in solids
Examples:
-Hot air rising, cooling, and falling (convection currents)
Turning on a burner and placing a glass of water NEXT to it and the water heating up

4. Radiation
Radiation: energy that is radiated or transmitted in the form of rays or waves or particles and
Examples
-Heat from the sun warming your face
-Heat from a light bulb
-Heat from a fire

5. LAW OF CONSERVATION OF ENERGY
Definition: This states that energy can change from one form to another, but it cannot be created or destroyed.
Important: When energy is used, it does not disappear……it simply changes to another form.

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

7. Examples of Mechanical Energy

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

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

10. 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.

11. Examples of Chemical Energy

12. 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.
