Energy is the driving force for the universe. Energy is a
quantitative property of a system which may be kinetic, potential,
or other in form. There are many different forms of energy.
One form of energy can be transferred to another form. The
laws of thermodynamics govern how and why energy is transferred.
Before the different types of energy resources and their uses
are discussed, it is important to understand a little about
the basic laws of energy...
Three Laws of Thermodynamics
There are three laws of thermodynamics.
The first law of thermodynamics, also called conservation
of energy, states that the total amount of energy in the universe
is constant. This means that all of the energy has to end
up somewhere, either in the original form or in a different
from. We can use this knowledge to determine the amount of
energy in a system, the amount lost as waste heat, and the
efficiency of the system...
What Is Energy? We can think of energy as anything that
can carry out an action or maintain a process. Without
energy, everything comes to a halt...
is defined as the ability to do work.
Work is defined as the transfer of energy....
