Kinetic energy is energy in _________.
motion
100
The energy an object has due to its mass and height and the pull of the Earth. Examples: Rollercoasters & hydropower dams
Gravitational Potential
100
Locations of: Highest PE & Highest KE?
Highest PE: D
Highest KE: C
100
KE + PE = ______
Mechanical Energy (technically total energy)
200
PE depends on an object's mass and _______
position
**only gravitational depends on height
200
KE depends on an object's mass and _______
speed
200
The energy stored in between atoms. Examples: Fuel, batteries, and food.

The higher your marble is, the more gravitational potential energy it has. Once you drop it, that gravitational potential energy turns into _____ causing the marble to be able to move through the hills, loop de loop, and other parts of the coaster to the end and land in the cup.
kinetic energy
300
Assuming they have the same mass, which ball has more gravitational potential energy and why?
The green one because it is higher.
300
As potential energy increases, Kinetic energy ____
decreases
300
The energy a substance has due to the vibration and movement of molecules. Also known as heat.
Thermal energy
300
Locations of: PE is actively increasing? KE is actively increasing?
PE increasing: A
KE increasing: E
300
KE + PE = ME (mechanical energy) or TE (total energy)
so 50 J + 50 J = 100 J
anywhere 1/2 uphill or 1/2way downhill where KE & PE would be equal.
400
How can this archer increase the amount of elastic potential energy his bow has?
Pull the arrow back more, stretching the string more.

Explain how the number of snowmen Burt (the yeti in the Gizmo) destroys relates to potential energy of the sled.
**Reminder this is the KE category so you should have that in your answer!
The higher you drag Burt, the more PE he has. The more when his PE is higher, there is more available to get transformed into KE and therefore he can destroy more snowmen.
400
Stored in the nucleus of an atom. The most concentrated form of energy.
Nuclear Potential
400
Locations of: PE is actively decreasing? KE is actively decreasing?
PE decreasing: E
KE decreasing: A

Label each scenario as an example of Kinetic (KE) or Potential (PE) energy.
1. Pressing the brakes on your bike and feeling them get hot.
2. The lunch sitting on your plate waiting to be eaten.
3.The energy of the trampoline springs getting ready to propel you up into the air.
4. Blowing air on hot soup to cool it down.
5. Throwing a ball.
6. Sitting on a bench waiting for a friend.
7. The energy stored in your Nintendo Switch battery before you get a Victory Royal on Fortnite.
8. The sound produced by the music playing through the speakers as you play your favorite song.

In your own words, compare and contrast Kinetic and Potential Energy by giving at least one similarity and one difference.
Both Kinetic and Potential are types of energy so they are the ability to do work or cause change and they are both impacted by the mass of the object they are acting on. However, Kinetic energy is energy in motion and Potential energy is energy stored waiting to be used.
