Ways Energy can behave:

1) Potential Energy is the energy of position. An object's mass and height give an object its potential energy. The greater the mass or the higher an object is, the more P.E. an object has.

Potential Energy = (mass)(gravity)(height) or P.E. = mgh

2) Kinetic Energy is the energy of movement, motion. An object's mass and speed/velocity determine its kinetic energy. The greater the mass and the more speed an object has, the more K.E. an object has.

Kinetic Energy = 1/2(mass)(velocity)(velocity) or K.E. = 1/2 mv²

Potential/Kinetic Energy Videos

Watch the videos and answer the questions underneath them in your science notebooks.

A. 1. What is happening when potential energy is converted to kinetic energy? Describe the actions.

2. Pretend you are an animator; create a cartoon of your own involving Potential and Kinetic Energy, and be sure to label both PE and KE.

B. 1. Kinetic energy increases when the ____ and/or ______ of an object increases.

2. Potential energy increases when the ____, ______ or ___________ of an object increases.

3. Give an example of Potential Energy converting to Kinetic Energy, and an example of KE converting to PE. You can either write a short paragraph or draw an illustration/cartoon of this.

C. 1. ______ is the ability to do work.

2. Energy cannot be _______ or _________, it can only be ______ or ___________.
3. Energy can take two forms: _________ Energy and ________ Energy.
4. _________ Energy is stored, whereas ______ Energy is based on motion or speed.
5. Give an example of PE and an example of KE; draw a picture!

D. 1. What is the law of conservation of energy? Put it into your own words.

2. Energy is __________ from one type to _______.
3. At the bottom of the rollercoaster, describe the Potential Energy and why this is.
4. Kinetic Energy deals with the energy of velocity or _____.

E. Energy in a Roller Coaster Ride

"This interactive roller coaster ride produced by WGBH illustrates the relationship between potential and kinetic energy. As the coaster cars go up and down the hills and around the loop of the track, a pie chart shows how energy is transformed back and forth between gravitational potential energy and kinetic energy."

How does the PE and KE change at each of the 6 steps? Think of the position and speed at each position.
