7

Potential Energy - Stored Energy

  • Baseball pitchers store up energy before throwing a powerful pitch

media

8

Kinetic Energy - Energy Relating to Motion

  • When the pitcher throws the ball, potential energy is transformed into kinetic energy.

media

9

Mechanical Energy - Sum of PE+KE

  • When you add potential and kinetic energy together you get mechanical energy

media

10

​Gravitational Potential Energy

  • Energy stored due to an object's position above ground.

  • ​The higher off the ground an object is, the more potential energy it has.

Fill in the blanks: The Law of Conservation of Energy states that energy cannot be cr____d or de______d 

12

​Law of Conservation of Energy

  • Energy cannot be created or destroyed.

  • This means that the total amount of energy in the universe will always stay the same.

    ​If energy cannot be created or destroyed then energy must be transFERRed between objects or transFORMed into a different type of energy entirely.

13

​Procedure:

  • ​Open the Phet Energy Skatepark simulation and select INTRO

  • ​Click the green plus next to Energy in the top left corner.

  • ​Select the Pie Chart box in the top right corner

media

14

​Procedure:

  • Drag the skater to the top of one side, then let them go.

  • Observe the energy bar graph as they go back and forth.

  • Don't touch any other dials just yet
