What is Energy

• Physicists, who are scientists who study force,
  motion and energy, say that energy is the ability
  to do work, and work is moving something against
  a force, like gravity.
• In physics, energy is the ability to do work, or
  the ability to move or elicit change in matter.
  In effect, the amount of energy something has
  refers to its capacity to cause things to happen.
• Measure of the ability of a body or system to do
  work or produce a change, expressed usually in
  joules or kilowatt hours (kWh).

Forms of Energy

Mechanical Energy
In the process of doing work, the object that is
doing the work exchanges energy with the object
upon which the work is done. When the work is
done upon the object, that object gains energy.
The energy acquired by the objects upon which
work is done is known as mechanical energy.
6
Electrical Energy
A form of energy that is produced when electrons
move from one place to another place. Electrical
energy is the energy newly derived from electric
potential energy. When loosely used to describe
energy absorbed or delivered by an electrical
circuit (for example, one provided by an electric
power utility) "electrical energy" talks about
energy which has been converted from electrical
potential energy.
7
Chemical Energy
Chemical energy is the potential of a chemical
substance to undergo a transformation through a
chemical reaction to transform other chemical
substances.  Energy that is available for release
from chemical reaction.

Electromagnetic Energy
Light is a form of electromagnetic
energy. Electromagnetic energy is also carried
gamma rays, xrays, ultraviolet rays, visible
light, infrared rays, micro Radio Waves. TV
waves, etc.

Thermal Energy
In thermodynamics, thermal energy refers to the
internal energy present in a system by virtue of
its temperature. Thermal energy is the energy
that comes from heat. This heat is generated by
the movement of tiny particles within an object.
The faster these particles move, the more heat is
generated. Stoves and matches are examples of
objects that conduct thermal energy.
