Basic Forms of Energy

What is energy?

• The ability to make something move or change.

• A measure of the temperature of an object.

• A type of force that acts on objects at rest.

• The total amount of matter in an object.

What type of energy is produced by a radio, siren, and television?

• Light energy

• Nuclear energy

• Sound energy

• Thermal energy

What is an example of kinetic energy?

• A moving car.

• A parked bicycle.

• A stationary rock.

• A book on a shelf.

What is kinetic energy?

• The energy of rest.

• The energy of motion.

• The energy of position.

• The energy of heat.

What is an example of potential energy?

• A stretched rubber band.

• A moving car.

• A flowing river.

• A burning candle.

What is an example of electrical energy?

• Electricity powering a light bulb.

• A moving car on a highway.

• A book on a shelf.

• A person running a marathon.

What is an example of energy transformation?

• A battery converting chemical energy to electrical energy.

• A light bulb converting electrical energy to thermal energy.

• A car engine converting mechanical energy to sound energy.

• A solar panel converting thermal energy to chemical energy.

What is potential energy?

• Energy stored in an object due to its position.

• Energy of motion in an object.

• Energy released during a chemical reaction.

• Energy that can be converted into heat.

What is electrical energy?

• Energy caused by the movement of electrons.

• Energy stored in chemical bonds.

• Energy produced by nuclear reactions.

• Energy derived from solar radiation.

What is the relationship between kinetic and potential energy?

• They can convert into each other; for example, a falling object converts potential energy to kinetic energy.

• Kinetic energy is always greater than potential energy.

• Potential energy is only present in stationary objects.

• Kinetic energy can never be converted to potential energy.
