Forms 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 electrical.

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 the stored energy in an object due to its position or state. For example, a rock at the top of a hill has gravitational potential energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of an object. It is the total kinetic energy of the 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 during a chemical reaction.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices like lights and computers.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light. It can travel through space and is used in solar panels.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in food to mechanical energy in muscles.

Front

What is an example of energy transformation in nature?

Back

An example is photosynthesis, where plants convert radiant energy from the sun into chemical energy stored in glucose.
