2. S.P.I 0507.10.1 Differentiate between potential and kinetic energy.

3. Academic Vocabulary Energy The ability to perform work or change an object Law of Conservation of Energy Energy may change form but it cannot be created or destroyed Potential Energy Energy stored in the position or structure of an object Kinetic Energy The energy of a moving object

4. I DON’T HAVE ANY ENERGY! Have you ever said… “I am so tired! I don’t have any energy!” Just what do you mean?

5. What is energy? Can you name some elements? Energy The ability to perform work or change an object When you are low on energy, you probably cannot do much work. But… WHAT IS WORK? Work is the measurement of the energy used to perform a task.

6. What is energy? Can you name some elements? We have energy but did you know objects also have energy? An example of an object with energy would be a slinky. When you stretch a slinky and let it go, it pulls itself back to its original shape.

7. Potential Energy Can you name some elements? Energy does not have to involve motion. When the slinky is stretched, it has energy but it is not moving. It has the potential to do work. Potential Energy The energy that is stored in the position or structure of an object

8. Potential Energy There are several different kinds of potential energy. Chemical Potential Elastic Potential Nuclear Potential Gravitational Potential

9. Potential Energy Can you name some elements? Any time an object is raised above the ground, the potential energy it gains is gravitational potential energy. The greater the object’s height and weight, the more gravitational potential energy it gains.

10. Kinetic Energy Once an object is in motion, it has energy of motion Kinetic Energy The energy of a moving object A roller coaster has kinetic energy when it is moving up or down on a ramp. A moving object can do work on any object it touches.

11. Kinetic Energy The amount of kinetic energy an object has depends on its velocity. The faster the object is moving, the more kinetic energy it has. The amount of kinetic energy an object has also depends on its mass. An object with a greater mass will have more kinetic energy than an object with a smaller mass.

12. Kinetic Energy There are several different kinds of kinetic energy. Heat Light Electricity Sound

13. Energy All forms of energy have one thing in common… THEY CAN ALL PERFORM WORK!

14. Energy Some forms of energy change the structure of objects rather than move them, but this is still work. For example, heat can melt or boil substances.

15. Changing Potential Energy into Kinetic Energy Potential energy can change into kinetic energy very easily. PotentialKinetic

16. How can energy change? Energy does not always keep its form. Energy is transferred when it passes from one object to another. The kinetic energy if transferred from one ball to another when the collide.

17. How can energy change? The first ball slows down or stops as it collides with the second ball. The kinetic energy is transferred to the second ball and the second ball begins to move.

18. How can energy change? Energy can also be transformed when it changes from one form to another. For example, when you flip a light switch to turn a light on, you are transforming electrical energy to light energy.

19. How can energy change? Energy can NOT be created or destroyed. It can only change forms. This is called the law of conservation of energy. A roller coaster, for example, can not gain kinetic energy without losing potential energy. Law of Conservation of Energy Energy can not be created or destroyed; it can only change forms. THIS WILL BE ON YOUR TEST!!!
