what are the two main types of energy?

After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. ​Kinetic energy is defined as the energy of a moving object.

Crude oil, coal, wind and natural gas are all primary energy sources. Electricity is not a primary energy source, it's an energy currency (see electricity as an energy currency for an in depth discussion). Likewise, secondary fuels are also energy currencies and aren't primary energy sources, they must be made.

Types of energy refer to different types of potential (chemical, nuclear, etc.) and kinetic (heat, sound, etc.) ... Potential energy comes in forms that are stored, including - Chemical, Gravitational and Nuclear. Kinetic energy forms are doing work - Like electrical, heat, light, motion and sound.

Forms of energy are just different types of energy such as heat, light, sound, kinetic and chemical. Energy resources are stores of a particular type of energy. Examples of energy resources include sunlight, wind, waves, coal and oil. Chemical energy is a type of energy.

Thermal energy transfer involves the transfer of internal energy. The three types of thermal energy transfer are conduction, convection and radiation. Conduction involves direct contact of atoms, convection involves the movement of warm particles and radiation involves the movement of electromagnetic waves.

The branch of science which deals with the interaction of matter and energy is called physics. There are Two Main Branches of Physics, Classical Physics and Modern Physics. Further sub Physics branches are Mechanics, Electromagnetism, Thermodynamics, Optics, etc..

Although there are many specific types of energy, the two major forms are Kinetic Energy and Potential Energy. Kinetic energy is the energy in moving objects or mass. Examples include mechanical energy, electrical energy etc.

For example, primary energy sources include petroleum, natural gas, coal, biomass, flowing water, wind, and solar radiation. ... Secondary energy cannot be harnessed directly from nature; rather, secondary energy is energy that has already been converted.

There are three main fossil fuels: coal, petroleum and natural gas. Coal is cheap and abundant, but it releases a lot of pollutants when burned.

Types of energy can be categorised into two broad categories – kinetic energy (the energy of moving objects) and potential energy (energy that is stored).

There are two main types of mechanical energy. They are motion energy and stored mechanical energy. Motion energy: This is the energy something has because it is moving (eg a speeding cricket ball).
