• d

The most potential energy is at

• a

• b

• c

• d

When a pendulum swings, at which point is potential energy at its greatest?

• 1
• 2
• 3
• 4

Energy stored by something that can stretch or compress, like a spring or a trampoline is called:

• elastic potential energy

• gravitational potential energy

• elastic kinetic energy

• gravitational kinetic energy

As mass increases, KE ...

• increases
• decreases
• stays the same

As the velocity of an object decreases its KE will...

• increase
• decrease
• stay the same

energy cannot be created or destroyed, only transferred

• Law of conservation of matter

• Law of conservation of energy

• Law of energy transfer

• Law of the universe

This is the standard international unit for energy

• newton

• joule

• kilogram

• m/s/s

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

Heat transfer always moves ...

• cold to hot

• east to west

• hot to cold

• north to south
