Science: Forms of Energy



FORMS OF ENERGY
MEANING
USES
1. Chemical Energy
Is the potential of a chemical substance to undergo a transformation through a chemical reaction or to transform other chemical.
The most common use of chemical energy is the food we consume to generate enough energy to live, work, think.
Plants convert solar energy into chemical energy through a process called photosynthesis.

Batteries use chemical energy and convert it to electrical energy to power electric devices, motors, etc.

2. Mechanical Energy
A combination of kinetic and potential energy resulting from the force of gravity or the movement or release of a machine component, such as a spring, clamp or wheel.
used in generators to create electrical energy, it is used in manual labor, anything really that requires movement. Levers, rope-and-pully systems
3. Radiant Energy
Energy that is transmitted in the form of (electromagnetic) radiant energy that exists or the absence of matter.
Most commonly used in the fields of radiometry, solar energy, heating and lighting, but is also sometimes used in other fields (such as telecommunications)
4. Thermal Energy
Is the part of the total internal energy of a thermodynamic system or sample of matter that results in the system temperature. This quantity may be difficult to determine of even meaningless unless the system has attained its temperature only through cooling, and not been subjected to work input or output.
Used in all sorts of ways. Use it to keep warm (by heating structures and vehicles) prepare food (both at home and commercially, industrial applications.) We can convert thermal energy to electrical energy. Thermal energy from the sun supports life on this planet.
5. Electrical Energy
is the result of the interaction of subatomic particles with electromagnetic force. Within an atom, electrons and protons create a charge. This charge can be transferred between bodies using direct contact with a conductive material like a wire.

used throughout the world to power devices, appliances and methods of transportation utilized in daily life. To make things operate, electrical energy must be emitted from energy sources such as power plants, to enable an object to consume the power it needs to function. As a result, the electrical energy permits people to watch television in their home, or purchase soda from a vending machine because the electrical energy is available.
