Select ALL the examples of potential energy
a person running
a bowstring of the bow and arrow pulled back
a snowboarder standing at the top of a ski slope
a basketball going through a net
Select ALL the examples of kinetic energy
Driving a car down a mountain
Basketball going through a net
Chemical energy stored in a battery
The arrow released traveling through the air
How does kinetic energy differ from potential energy?
Kinetic depends on position of an object
Kinetic depends on the motion of an object
Kinetic depends on the location of an object
The equation for work is
work = power x mass
work = power / time
work = force x distance
work = distance x time

Think about a pan of water sitting on an electric stove. The stove is then turned on to high.
How is heat transferred from the stove to the pan?
conduction
convection
radiation
temperature
Sam placed a glass of water in the refrigerator. After about an hour he took it out and found it to be colder.
What is the most likely thing that happened?
the cold that was in the refrigerator transferred into the water
the particles in the water started to move faster
the cold from the refrigerator radiated into the glass
the heat that was in the water transferred out into the refrigerator
