Potential and Kinetic Energy in the real world.

2. Energy Energy: the ability to do work
Work: the use of force to move an object. Depends on the amount of force and the distance the object traveled
The formula for work is W = F x D.

3. Energy Transformation
Law of Conservation of Energy: energy cannot be created nor destroyed It must transform into another type of energy!

4. Potential Energy
Stored energy; energy an object has because of its position (height) or condition (mass)

5. Examples of Potential Energy
Gasoline in a vehicle gas tank
Nutrients in food

6. Kinetic Energy Energy an object has because of its motion.
žDepends on mass and speed.

7. Examples of Kinetic Energy
Coaster full of people = more mass = greater KE than empty coaster
High coaster drop = greater speed and total energy

8. Mechanical Energy the sum of kinetic and potential energy
Examples: --waterfall --sound waves --wind --moving cars

9. Draw and Label the coaster!
F- potential energy
G- half potential and half kinetic
H- all kinetic
K- half potential and half kinetic
