Unit 2 EXAM : Energy

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, which can travel through space without needing matter.

Front

How does the speed of an object relate to its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What happens to the total amount of energy when a candle burns?

Back

The total amount of all types of energy is conserved when the candle burns.

Front

What is an insulator?

Back

An insulator is a material that prevents electricity from passing through it, such as rubber used in electrical wires.

Front

At which point is Pablo's kinetic energy the greatest while sledding down a hill?

Back

Pablo's kinetic energy is greatest at Point D.

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) caused by differences in temperature.

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 in an object due to its position or state.

Front

What is the law of conservation of energy?

Back

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