  5. 5. POTENTIAL ENERGY ● Mechanical energy due to position ● Example: book sitting on your desk.
  6. 6. CHEMICAL ENERGY ● Is stored in the bonds between atoms ● Examples: ● the foods we eat gives us energy. ● Cars use energy used in gasoline
  7. 7. NUCLEAR ● When atoms break apart. ● Example: Nuclear power plants
  8. 8. THERMAL ENERGY ● Moves from one object to another as heat. ● Example: Friction
  9. 9. Electrical Energy ● Results from the movement of electrons ● Example: TVs and lights
  10. 10. Energy Changes ● From one form to another ● All forms of energy can be used to create forces to do work ● Each type of energy can be changed into thermal energy.
  11. 11. Law of Conservation ● Energy is not created or destroyed It is conserved ● Example: Bouncing a ball the ball stops bouncing and the floor absorbs the energy of the ball.
