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.

What is kinetic energy?

Back

Kinetic energy is the energy of motion. It depends on the mass and velocity of an 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 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 thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance. It is often associated with heat.

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 energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, particularly in the nucleus of an atom.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including light. It can travel through space.

Front

What is the difference between renewable and non-renewable energy?

Back

Renewable energy comes from sources that can be replenished naturally, like solar or wind energy. Non-renewable energy comes from sources that can deplete, like fossil fuels.
