Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by sources like the sun, light bulbs, and fire.

Front

What is sound energy?

Back

Sound energy is produced when an object vibrates, creating waves that travel through air, water, or solids.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, enabling it to do work.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often associated with heat.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons, commonly used to power devices.

Front

Can sound energy travel through a vacuum?

Back

No, sound energy requires a medium (like air, water, or solids) to travel and cannot move through a vacuum.

Front

What is an example of an object that uses only mechanical energy?

Back

A wind-up toy uses only mechanical energy to move.

Front

What is the primary source of light energy on Earth?

Back

The primary source of light energy on Earth is the Sun.

Front

How is thermal energy transferred?

Back

Thermal energy is transferred through conduction, convection, and radiation.
