Energy

What is potential energy?

• The energy of an object in motion.

• The energy stored in an object due to its position or state.

• The energy released during a chemical reaction.

• The energy associated with the temperature of an object.

What is thermal energy?

• Thermal energy is the energy that comes from heat, created by the movement of particles in a substance.

• Thermal energy is the energy stored in chemical bonds of molecules.

• Thermal energy is the energy associated with the gravitational pull of an object.

• Thermal energy is the energy produced by electrical currents.

What is a conductor?

• A material that allows electricity or heat to pass through easily.

• A material that prevents electricity or heat from passing through.

• A type of insulator used in electrical circuits.

• A device that generates electricity.

What is non-renewable energy?

• Energy that comes from sources that can be replenished quickly, such as solar and wind power.

• Energy derived from sources that cannot be replenished in a short period, like fossil fuels.

• Energy that is produced from nuclear reactions and is considered renewable.

• Energy that is generated from geothermal sources and is sustainable.

What is light energy?

• A form of energy that is invisible to the human eye

• A form of energy produced by sources like the sun and light bulbs

• A type of energy that can only be felt, not seen

• A form of energy that is only produced by artificial sources

What is electrical energy?

• The energy caused by the movement of electrons, powering devices like lights and computers.

• The energy stored in batteries when not in use.

• The energy produced by solar panels only.

• The energy that is generated by wind turbines exclusively.

What is the source of almost all light on Earth?

• The moon

What does it mean to measure the volume of sound?

• Determining the frequency of the sound waves.

• Measuring the distance sound travels in a given time.

• Determining how loud or soft the sound is.

• Assessing the pitch of the sound.

What is renewable energy?

• Energy that comes from fossil fuels

• Energy that can be replenished naturally, such as solar, wind, and hydroelectric power
