Forms of Energy

Front

What is thermal energy?

Back

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

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

Front

What is sound energy?

Back

Sound energy is the energy produced when an object vibrates, creating sound waves that travel through the air or other mediums.

Front

What is light energy?

Back

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

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air to water.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface, such as a mirror or water.

Front

What is absorption in terms of energy?

Back

Absorption is the process by which an object takes in light or other forms of energy, rather than reflecting or transmitting it.

Front

What are the two main forms of energy the sun provides?

Back

The sun provides light energy and thermal energy.

Front

What is the relationship between vibration and sound energy?

Back

When an object vibrates, it creates sound waves, which is how sound energy is produced.
