What is the law of conservation of energy?
The rule that energy cannot be created or destroyed, just transferred or converted.
100

What are the three examples of potential energy?

Chemical potential energy, elastic potential energy, and gravitational potential energy

100

What is the unit used for Work and Energy?

Joules 

100

What part of the catapult holds potential energy?

the rubber band when stretched

200
What is the difference btn kinetic energy and potential energy?
kinetic=energy of motion potential=stored energy
200
When will a ball have maximum potential energy?
When the ball is positioned at the edge of the table about to fall off.
200

What is the equation for Work?

W=Fd

200

When you throw the airplane, what is the potential energy there? 

Your muscles contracting

300
Word which means to change from one form to another?
Convert or transform
300
As a ball falls to the ground which statement best describes its increase or decrease in potential and kinetic energy?
potential energy is converted into kinetic energy OR potential energy decreases as kinetic energy increases
300

What is the Equation for Potential Energy?

PE=mgh

300

When you lift the catapult to use it, are you doing work? What kind? (negative, positive)

Yes, positive work

400

What is the definition of work?

when a force is applied to an object and the object moves in the direction of the applied force

400
Car A and B are both driving at 30 mph. I want to know which has more kinetic energy. What will you ask me?
What are the masses of the cars?
400

What is the equation for KE?

KE=1/2mv2

400

Describe the transfer of energy Ms. Rudolph was trying to show you through this lab

Work on rubber band makes potential energy, this is converted to kinetic energy as the airplane flies through the air

500

How are work and energy related?

Work can be done to increase energy in a system

500

What are three examples of kinetic energy?

Open answer

500

What is the equation used for conservation of energy problems?

TE = KE + PE

500

What is another form of potential energy that could launch a paper plane?
