  2. Objective Today you will be able to identify examples of each form of energy and answer at least two questions about each form of energy, in a quiz following each topic lesson. Click to continue

  3. What Are the Forms of Energy? • Mechanical • Electrical • Thermal • Sound • Radiant 6. Learn more Click the picture to learn about each form of energy. LearnMore!

  4. Mechanical Energy • This is energy due to an objects motion and position. • Mechanical energy includes kinetic and potential energy. • An object has mechanical energy under two conditions- 1. it is in motion 2. If it is relative to a zero potential energy position CONTINUE

  5. Mechanical Energy Continued • Kinetic and Potential Energy • Kinetic energy is energy due to motion • Potential energy is stored energy in a given position Examples of mechanical energy: 1.Moving car 4. Book on a shelf 2.Baseball in motion 5. A weight over your head 3.A sling shot drawn back 6. A flying kite Click on me to continue!

  6. Mechanical Energy Quiz 1. Is mechanical energy the energy produced from movement? 2. Is a car sitting at a red light an example of mechanical energy? YES NO YES NO Back to main menu

  7. Electrical Energy • Electrical energy comes from any energy put out by electricity. • This is most common and most useful type of energy. If a device has a power cord or batteries it produces electrical energy. • The energy itself is not visible, but the device is visible. • Examples of electrical energy are- Light bulb power cord Batteries in a flashlight hair dryer Toaster microwave CONTINUE

  8. Electrical Energy Quiz • Does a lamp produce electrical energy? 2. Which device does not produce electrical energy? • Frying pan • Flashlight • Hair dryer YES NO Back to main menu

  9. Thermal Energy • Thermal energy relies on the temperature of an object; the energy produced by heat. • It is not the most useful form of energy because objects do not easily remain heated. • It differs from radiation, because radiation is energy being reflected or absorbed due to heat. Thermal energy is the energy made from heat. CONTINUE

  10. Thermal Energy Examples Four common examples of thermal energy are- • A pot of boiling water • Burning coals in a grill • The microwaves in a microwave oven • A geyser; a spring ejecting water due to heat CONTINUE

  11. Thermal Energy Quiz • Is thermal energy the same as radiation? • Which of the following is an example of thermal energy? • The sun • Pot of boiling water • Hair dryer YES NO Back to main menu

  12. Sound Energy • Sound energy is the energy produced from the vibrations of a disturbance of matter. • Sound actually travels by waves. Sound must travel through a medium; solid, liquid, or gas. • Sound produces the least amount of energy. The waves are not strong enough to carry very much energy. CONTINUE

  13. Sound Energy Examples Some common examples of sound energy are- • Sound produced by a guitar string • The sound from drums being hit • A dog barking • Your stereo blasting • Aircraft • A sports car roaring down the street All of these cause vibrations and transfer energy that you can hear. CONTINUE

  14. Sound Energy Quiz • Is sound energy the best form of energy available to us? • No, it is better to see energy rather than hear it. • Yes, we learn more by hearing. • No, sound waves transfer the least amount of energy making sound energy least efficient. 2. Sound energy is the energy produced by a disturbance of matter. True or False. Back to main menu

  15. Radiant Energy • Radiant energy is the energy from electromagnetic waves. • It is emitted or absorbed by a source/object into the environment. There are a large number of examples or sources of radiant energy, the main thing is heat emitted or absorbed by an object. It is one of the most common forms of energy. • Radiation is the only form of energy that travels purely through space. • It can be visible or invisible. CONTINUE

  16. Radiant Energy Examples • A campfire • Solar energy • The sunlight (ultraviolet rays and infrared radiation) • X-rays • Radio waves • Microwaves • Heat emitted off hot cars or bricks • Light and heat given off by a light bulb CONTINUE

  17. Radiant Energy Quiz • Is radiant energy a common source of energy? • Which of the following is an example of radiant energy? • A car giving off heat • A furnace heating your house • The sun burning your skin • All of the above YES NO Back to main menu

  18. Learn More! • Click the link below to answer the following questions. 1. What is the definition of energy? • The hyper feeling you get from to much sugar. • The ability to do work. • A super cool power. 2. Are the forms we learned, the only possible forms of energy? • Yes • No Back to main menu or click to continue

  19. Energy Review Do you know what form of energy each picture represents? 1. 2. 3. 4. 5. Continue to the next slide to see if your guess was correct. Continue

  20. What forms of energy are they? • Electrical energy • Radiant energy • Sound energy • Mechanical energy • Thermal energy Continue
