Energy Transfer

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

Which object has kinetic energy?

Back

A rolling bowling ball has kinetic energy because it is in motion.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to its temperature.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases) caused by heating and cooling.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through empty space without the need for a medium.

Front

In which direction does heat move?

Back

Heat moves from warmer objects to cooler objects.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.
