Forms of energy and Energy Transformations

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, and chemical.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and velocity 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 nuclear fusion?

Back

Nuclear fusion is the process of combining two light atomic nuclei to form a heavier nucleus, releasing energy in the process.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a heavy atomic nucleus into smaller nuclei, accompanied by the release of energy.

Front

How does a windmill work?

Back

A windmill converts kinetic energy from the wind into mechanical energy, which can then be transformed into electrical energy.

Front

What are the two main types of energy?

Back

The two main types of energy are kinetic energy (energy of motion) and potential energy (stored 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, which can be released during a chemical reaction.
