1.2 Forms of energy

Energy can be defined as the capacity to do work. It is governed by the law of conservation of energy from the first law of thermodynamics which states that energy can be neither created nor destroyed. However, energy can change forms and can flow from one place to another.

Energy is found in nature in many forms, including:

• Kinetic Energy which is energy associated with mass in motion
• Potential Energy which is energy associated with position in a force field such as a gravitational, electric, or magnetic field
• Chemical Energy which is energy stored in certain materials that can be released by chemical reactions
• Thermal/Heat Energy which is energy associated with random molecular motions within a medium; often associated with temperature
• Radiant Energy which is energy carried by light and other electromagnetic radiation

After we have some some basic knowledge of different forms of energy, several other forms of energy, including Mechanical wave, Electric, Magnetic, Nuclear, Ionization, Elastic, Gravitational, Rest, Mechanical work, and their theories have also been listed here:
