What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibrations of electrically charged particles.

Front

How does a solar panel work?

Back

A solar panel absorbs light energy and converts it into electrical energy, which can be used to power devices.

Front

What is mechanical energy?

Back

Mechanical energy is the energy that an object has due to its motion or position.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

How is energy transferred?

Back

Energy can be transferred from one form to another, such as from mechanical energy to thermal energy.

Front

What happens when you rub a metal coin against a rock?

Back

Rubbing a metal coin against a rock transfers mechanical energy to the coin, causing it to become warmer due to the conversion to thermal energy.

Front

What is the role of vibrations in sound energy?

Back

Vibrations are the source of sound energy; when an object vibrates, it creates sound waves that travel through the air.

Front

How does a wind-up toy demonstrate energy transfer?

Back

A wind-up toy converts mechanical energy from winding the clip into additional mechanical energy that moves the toy.

Front

What is the relationship between energy and motion?

Back

Energy is required to cause motion; when energy is applied to an object, it can move or change position.

Front

What is the effect of heat on the movement of particles in a substance?

Back

Increasing heat energy causes particles in a substance to move more rapidly.
