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 chemical.

Front

What are the main forms of energy?

Back

The main forms of energy include kinetic, potential, thermal, chemical, electrical, nuclear, and radiant energy.

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

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 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 nuclear fission?

Back

Nuclear fission is the process of splitting a large atomic nucleus into smaller nuclei, releasing a significant amount of energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process of combining two small atomic nuclei to form a larger nucleus, releasing energy.

Front

How does a windmill convert energy?

Back

A windmill converts mechanical energy from wind into electrical energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.
