Front

The energy stored in an object is called ____________.

Back

Potential energy is the energy stored in an object due to its position or state.

Front

The faster an object moves the greater its ____________ energy.

Back

Kinetic energy is the energy of an object in motion, which increases with speed.

Front

The glow sticks produce light for a short amount of time. The light from the glow stick is a conversion from what to what?

Back

The light from the glow stick is a conversion from chemical energy to light energy.

Front

At what point does the roller coaster have the most Kinetic energy?

Back

The roller coaster has the most kinetic energy at point D, where it is moving the fastest.

Front

The Gulf Stream is a current that brings warm ocean water from the south to the north. What type of heat transfer is this?

Back

This is an example of convection, which is the transfer of heat through the movement of fluids.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot from being in a pot of boiling water.

Front

What is an example of radiation?

Back

An example of radiation is the heat from the sun warming your skin.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
