What is kinetic
100
This is an object's ability to do work.
What is energy?
200
The type of Energy that depends on mass and position
What is potential energy
200
Pedaling a bicycle.
What is mechanical energy?
200
As the speed of a falling object increases, its potential energy will _____________________.
What is decrease
200
This is the energy due to the compression or stretching of an object.
What is elastic energy?
200
This type of energy is stored energy.
What is potential energy?
300
Type of energy that depends on the speed of molecules.
What is thermal or heat energy
300
Explain the transformation of a book falling from table. Explain the type of energy and where it comes from.
What is Potential (due to the position of the book) to kinetic (motion of the book)
300
When you drop a book on the floor, what happens to its original potential energy?
What is the potential energy was transfered to kinetic and thermal energy
300
This is the energy due to an object's position in a gravitational field.
What is gravitational energy?
300
This type of energy is associated with motion.
What is kinetic energy?
400
Type of energy that depends on the flow of electrons
What is electrical energy
400
When you jump and are at your peak position, all of your energy is in this form.
What is Gravitational Potential Energy?
400
A basketball is dropped from a height of 2m and another identical basketball is dropped from a height of 4m. Which ball has more kinetic energy just before it hits the ground?
What is The basketball dropped from a height of 4m because it has more speed.
400
This is the energy that takes into consideration an object's mass and it's velocity.
What is kinetic energy?
400
State the Law of Conservation of Energy
What is Energy can not be created of destroyed it can only be transfered or tranformed.
500
Type of energy stored in bonds
What is Chemical energy
500
Explain the transformation that takes place to make a toaster plugged into an electrical outlet work.
What is the electrical energy from outlet transforms into thermal (heat from the toaster) and radiant (when the toaster get hot enough it will emmit light)

When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. Explain how the law of conservation of energy is obeyed.
What is During each bounce, some of the kinetic energy of the ball in transfered into thermal energy. As a result, energy is not created or destroyed, but only changes form so that the law of conservation of energy is obeyed.
500
When you were at the lab station that involved designing a skate park, you saw how these two types of energy worked together.
What are kinetic and potential energy?
