What Is Energy?
In physics, energy, the power for performing work by an individual unit. It can exist in kinetic, potential, electrical, Chemical, atomic, or many other forms. There are also, however, work and heat i.e., energy during the process of transference from a body to another
There is the potential energy, which is the sum of kinetic energy and potential energy over a definite time interval, and the potential energy, which is the sum of kinetic energy over a definite distance. Kinetic energy is the product of moving masses with their speed; that is, it is a result of a force. Potential energy is the result of the change in temperature on a fixed mass, when it is deformed from its original state. Thermal energy is heat energy and the amount of heating required to raise a fixed mass from a point at low temperature to a point at high temperature. Thus, thermal energy results in the production of mechanical energy.
The other major type of energy is the endothermic and exothermic energy. The exothermic energy comes from the radioactive decay of matter into heat. The endothermic energy is the only one produced by chemical reactions and is known to be the primary energy found in radioactive elements. The other types of energy are the thermal energy derived from heat, the electrical energy from electricity, chemical energy, magnetism, sound, and radiation, and the sound energy produced by the vibration of molecules. The entire world of energy is a highly complex field.
The study of energy has been one of the major branches of mathematics for many years and was the subject of many great minds. Albert Einstein was able to recognize the value of energy and said “The definition of energy is energy packed or concentrated in a space that does not change”. He did however further complicate things when he said “Einstein’s energy theory says that energy can be neither created nor destroyed but only transferred.”
People have also put forth many different theories as to the relationship between energy and matter. One such theory states that energy cannot be created or destroyed but can only be transformed. Another theory states that matter itself is composed of energy while still another theory states that energy is a kind of neutral field just like the ether that permeates all things. The problem with these theories is that they are not well understood and are widely differing subjects.
Now there are many different forms of energy that can be converted from one form to another when certain conditions are met. Kinetic energy is simply converted from moving objects using nothing but motion. Potential energy is a form of energy that is found in many different forms including light, sound, heat, x-rays, electricity, magnetism, and even nuclear fission and fusion. The conversion of kinetic energy into some other form of energy can be done through converting potential energy into kinetic energy, which then transforms to electrical energy, which then changes into gamma radiation and gamma rays. The final form of energy is thermal energy, which is simply the energy that is required to conduct some kind of movement.
