Unit 8 Review: Energy

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What type of energy is stored in food and fuels?

Back

Chemical energy is stored in the bonds of chemical compounds, such as food and fuels.

Front

What type of energy is released when a match is lit?

Back

Thermal energy is released when a match is lit, as the chemical energy in the match converts to heat.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

How do wind turbines convert energy?

Back

Wind turbines convert mechanical energy from wind into electrical energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and velocity.

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.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.
