How does energy relate to the real world?

4. Law of Conservation of Energy
Energy can be transformed from one form into another or transferred from one region to another, but energy cannot be created or destroyed.

How does this picture illustrate the law of conservation of energy?

6. What is energy?
Energy is the ability to cause change.
Mechanical energy is the energy an object has due to its motion or position.

7. Two Parts of Mechanical Energy
Potential Energy – energy that is stored in an object but is not being used.
Kinetic Energy – energy of motion.

8. An object that is not moving has potential energy.

9. Kinetic energy is the energy of motion.

10. Think Pair Share
How can you differentiate between potential and kinetic energy?

11. Forms of Potential Energy
Gravitational Potential Energy – depends on the object’s weight and height.

12. Elastic Potential Energy – stored in objects that are compressed or stretched.

13. Chemical Potential Energy – stored in the chemical bonds between atoms.

14. What effects the Kinetic Energy?
Speed
Faster speed = More Kinetic Energy
Mass
Greater mass = More Kinetic Energy
