Front

What happens to kinetic energy when an object comes to a stop due to friction?

Back

The kinetic energy is transformed into heat energy as a result of friction.

Front

What do the orange circles (+) represent in a diagram of an atom?

Back

The orange circles represent protons.

Front

What is the effect of increasing the kinetic energy of molecules on temperature?

Back

Temperature increases.

Front

How does a hot pan handle get heated?

Back

The pan is touching the hot burner, causing the entire pan, including the handle, to heat up.

Front

How is energy transferred on a roller coaster ride?

Back

Energy is transferred through changes in potential and kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

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

Front

What is the principle of energy conservation?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).
