potential energy
Potential energy is energy and object has based on its position or condition.
What is Kinetic Energy
Potential energy is also known as:
What is stored energy?
The type of energy was involved in our catapults:
What is Elastic Potential Energy
The science that deals with the structure of matter and how the universe behaves is called:

Answers will vary.
List 2 examples of kinetic energy.
Answers will vary.
Explain how you would use potential and kinetic energy to speed up a roller coaster?
Increasing the potential energy by increasing the height of the starting point.
The type of potential energy involved in something that is sitting at the top of a hill:
What is gravitational potential energy?
Matter is:
What is anything that takes up space in the world and has mass called?
Where does a roller coaster have the greatest potential energy?
A the highest point of the track.
Where does a roller coaster have the greatest amount of kinetic energy?
At the lowest point of the track
Is hydroelectric potential or kinetic energy and why?
Kinetic energy, because the water is moving.
Define chemical potential energy:
What is energy stored in the bonds of atoms and molecules?
The Particle Theory of Matter states that:
All matter is made up of tiny particles (atoms)
When does a rubber band have the greatest elastic potential energy?
When it is stretched
When does a snowboarder have the highest kinetic energy?
At the bottom of the hill?
When does a pendulum have the greatest potential energy and the least kinetic energy?
When the ball is in the middle or bottom position.
Can potential and kinetic energy be created?
What is the name of the related law of physics?
No energy can never be created or destroyed, it can only change forms.
What is Conservation of Energy?
Three of the states of matter and their characteristics are:
What are solid (particles are close together and only vibrate, retaining their shape)
liquid (particles are quite close, and particles can move around each other slightly, retaining the shape of their container)
gas (particles are farther apart and can move freely, but they retain the shape of a closed container)?
How does the height of an object affect its gravitational potential energy?
The higher an object is the more potential energy it has.
Explain how you would change a marble's potential energy into kinetic energy?
Answers will vary.
Explain the the relationship between kinetic energy and potential energy.
Which states of matter are related to hydraulic vs pneumatic power? Explain.
What are liquids vs gas? Liquids cannnot be compressed very much, but gas can, so hydraulic power is slower but more direct.
