1. Energy: Potential vs. Kinetic
EQ: How can you differentiate between potential and kinetic energy?

2. What is energy?
Energy is the ability to cause change.
There are 2 main types of energy: Potential & Kinetic

3. Potential Energy is energy that is stored in an object but is not being used.

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

5. Forms of Potential Energy
Gravitational Potential Energy – energy stored between the object and the earth
Depends on the object’s weight and height

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

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

8. Kinetic energy is the energy of motion.

9. An object that is in motion has kinetic energy.

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

Potential Kinetic

20. The kite flies high in the sky.
Question 8

Potential Kinetic

21. Potential energy can change into kinetic energy

22. What is energy transformation?
The change in energy from one form to another.

23. 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.

24. Changing Potential & Kinetic Energy

25. Explain what is happening in terms of potential and kinetic energy.
