Dear Readers, In this article I provide a list of Conversion of Energy by Major Devices which we use in our daily life which are very useful for us.
In most of the Competitive examinations like Railway NTPC, JE, ALP, Group D, SSC CGL, CHSL, Banking, FCI, State PSU, etc., science is a major part of General Knowledge. Most questions arise in the examination from List of all Inventions and discoveries, Chemical Formulas, List of all Inventions and discoveries, Important Minerals & Ores, Various Branches of science/Study of Different fields, etc.
Law of conservation of energy
The law of conservation of energy states that energy can neither be created nor destroyed. It only converted from one form of energy to another. This means that a system always has the same amount of energy unless it’s added from the outside.
Conservation of energy was distinct from conservation of mass; however, special relativity showed that mass is related to energy and vice versa by E = mc2, and any object with mass can itself be converted to pure energy, and vice versa.
E is the amount of energy in an object or system.
m is the mass of the object or system.
c is the speed of light .c =3 × 108 m/s
