A pot on a stove gets hot due to this type of heat transfer.
What is conduction?
100
An example of this type of energy is a nuclear power station.
What is nuclear?
100
Power relies on these two factors.
What are work and time?
100
When energy is transferred, some of it is always "lost" as this.
What is heat?
100
This type of energy is shown by an owl flying.
What is kinetic?
200
Air currents heat up and cool off due to this type of heat transfer.
What is convection?
200
A toaster heats toast up. This is an example of what type of energy?
What is thermal?
200

Work relies on these two factors.

What are force and object moving in direction of the force?

200
Trace the transfer of energy from the gasoline to the car moving.
What is chemical --> mechanical?
200
This type of energy is shown by a ball sitting at the top of a hill.
What is potential?
300
You get a sunburn due to this type of heat transfer.

A rock is poised on the edge of a cliff

What is gravitational potential energy?

300
True or False: Jessica lifts a box. She is doing work on the box.
What is true?
300
A generator is used to turn on a light bulb. Trace the energy conversion.
What is mechanical --> electrical --> light?
300
Without changing the amount of work, the amount of power can be changed by doing this.
What is completing it in less time?
400
You stand near a fire. You get warm due to this type of energy transfer.
What is radiation?
400
This is the energy that is at a maximum when a skater is at the lowest point and moving fast

What is kinetic?

True or False: Sam walks downstairs carrying a heavy box. He is doing work on the box.

What is false?

400
Wind is used to power a computer. Trace the energy conversion.
What is mechanical --> electrical?
400
This is the Law of Conservation of Energy.
What is Energy cannot be created or destroyed, only changed in form?
500
Water boiling in a pan heats up due to this type of energy transfer.
What is convection?
500

This type of energy happens when a spring is compressed

What is elastic potential energy?

500
Two students both do the same amount of work. Justin does it in 20 seconds and Zach does it in 15 seconds. This student has more power.
What is Zach?
500

This is the phenomenon that causes mechanical energy to be transformed into thermal energy

What is friction?

500
A hot object is put in contact with a cold object. Describe what will happen to the two objects over the next 12 hours.
What is heat will transfer from the hot to the cold until they are the same temperature?
