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.

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 the stored energy of an object due to its position or state. It can be due to height (gravitational potential energy) or shape (elastic potential energy).

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 or absorbed during a chemical reaction.

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is commonly used to power devices and appliances.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including light. It is the energy that travels through space.

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 an energy transformation?

Back

An energy transformation is the process of changing energy from one form to another, such as converting electrical energy into thermal energy.
