Types of Energy

Front

What is energy?

Back

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

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a rock at the top of a hill has gravitational potential 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 a substance.

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 during a chemical reaction.

Front

What is nuclear energy?

Back

Nuclear energy is the energy stored in the nucleus of an atom. It can be released during nuclear reactions, such as fission or fusion.

Front

What is mechanical energy?

Back

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

Front

How does energy conversion work?

Back

Energy conversion is the process of changing energy from one form to another. For example, a glow stick converts chemical energy into light energy.

What is an example of energy transformation in a roller coaster?

Back

As a roller coaster climbs a hill, kinetic energy is converted into potential energy. At the top, it has maximum potential energy.

What is the role of a lightbulb?

Back

A lightbulb converts electrical energy into light energy, providing illumination.
