  1. 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 ElectromagneticEnergy? 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.

  13. QUIZ TIME! What type of energy cooks food in a microwave oven? ELECTROMAGNETIC ENERGY What type of energy is the spinning plate inside of a microwave oven? MECHANICAL ENERGY

  14. QUIZ TIME! Electrical energy is transported to your house through power lines. When you plug an electric fan to a power outlet, electrical energy is transform into what type of energy? MECHANICAL ENERGY

  15. QUIZ TIME! What energy transformation occurs when an electric lamp is turned on? ELECTRICAL ENERGY  ELECTROMAGNETIC ENERGY

  16. What types of energy are shown below? Mechanical and Thermal Energy (Don’t forget friction)

  17. What type of energy is shown below? Chemical Energy

  18. What types of energy are shown below? Electrical, Mechanical and Electromagnetic Energy

  19. What type of energy is shown below? Chemical Energy (yummy)

  20. What type of energy is shown below? Thermal Energy
