What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, such as kinetic, potential, thermal, and more.

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work. For example, a ball held at a height has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. The faster an object moves, the more kinetic energy it has.

Front

What is sound energy?

Back

Sound energy is produced by vibrations and travels through air, water, or solids. Examples include music and voices.

Front

What is light energy?

Back

Light energy is a form of electromagnetic radiation that is visible to the human eye. It allows us to see the world around us.

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 stored in the bonds of chemical compounds, like food and fuel. It is released during a chemical reaction.

Front

What is mechanical energy?

Back

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

Front

What is the difference between sound and light energy?

Back

Sound energy travels in waves through a medium (like air), while light energy travels in electromagnetic waves and can move through a vacuum.

Front

What is an example of a device that produces both sound and light energy?

Back

Fireworks produce both sound (the bang) and light (the colorful explosions in the sky).
