Energy
The energy that provides us with light and Tattiynha tambourine and take us from one place to another, where it allows extraction of our food from the land and prepare it who put the money in our hands and runs Bmntaul wheel machines that we use to serve. It is the ability of a material to allow the forces able to accomplish a particular job, it is also the ability to produce effective or external system activity, an abstract entity who does not know only through transformations, as it is a physical quantity in the form of heat or a mechanical movement
Energy definition
Known in physics as the ability to work and end the mission and filled. For example, to increase the speed of a car or carrying a rock requires any work. The calculated energy and the job itself the measuring unit. Combines and lost individuals to distinguish between energy and the ability and strength. The ability to do the job is the average. Power is the payment or attraction being done by the human body.
The size of the labor force strongly linked to the road and in length which Athrkha body. Energy associated with moving so-called mechanical energy.
Hence, I will enumerate the types of energy inventory and not the explanation:
Energy types:
Chemical energy
Mechanical energy
Thermal energy
Solar Energy
Nuclear Energy
Electric power
Photovoltaic
Energy sources
Human desire to save energy, the scientists searching for several other energy sources, and from these sources:
1) solar energy: utilized through direct heating in water heating, heating and cooking processes, and can be converted directly to (Taqhkahrbaúah) mediated by solar cells
2) fossil fuel: is the coal, oil and natural gas, and stores this fuel (chemical energy) can take advantage of them when burned, and fossil fuels is the energy source of the president, accounting for over 90% of the energy used today, but it is a depletable source, and because of problems environmental pollution, the search actively for the provision and development of other energy sources
3) mechanical sources: They are waterfalls, dams and movement (tidal), wind energy, and therefore held plants (electricity generation) when dams, waterfalls and areas of high tides and strong winds across to exploit the mechanical payment in operating turbine power
4) renewable or clean or alternative energy: include wind energy and wind and solar energy, water or energy waves and groundwater in the ground and biomass energy, which is inexhaustible energies
5) geothermal energy is drawn from the high temperature in the underground, and in some areas will be this (underground energy) near the surface thus are found hot springs, in Iceland, for example - are spread these springs, and utilized for the purposes of heating and
6) chemical energy: chemical energy in batteries exploited to generate electricity. In accumulators used in a mobile phone which produces electricity from a chemical reaction. Also in the energy that exploit the hydrogen and oxygen to produce electricity through a chemical reaction electric cells.
7) nuclear energy: produce for (nuclear fission) in nuclear reactors, and utilized in the conduct of ships and submarines and generation (Power), highlighted the negative aspects (radioactive waste) generated, and the problem of disposal, and controls high safety measures to prevent the explosion of the reactor, or leakage of radiation him. A classification of energy and resources is based on the possibility that renewed energy and continuity 1. conventional energy or depleting: include coal, petroleum, natural gas, metals and chemicals, which are depleted because they can not be manufactured again or replaced again in a short time
Summary
The energy is very important, but at this time is different from what it was in past centuries. The few prices, and availability of huge amounts of fuel in the market led to wasteful energy consumption, and lack of rationalization and savings. We must search for new sources of non-depleted and non-harmful to the environment
Summary
Energy is defined as the ability to work and the completion of the task or job is, as it is in many things such as the speed of the car or carry a rock, it requires any work, and the energy and the workpiece is calculated in the same unit of measurement, and that a lot of people do not distinguish between power and energy capacity, where the capacity is the rate do the job, as the force is a process in which the payment or attraction to things made by man his body is happening, and that the job of any energy depends on the severity of the force as well as the nature of the road and the distance traveled, which is driven by the body, as The energy that has been integrated to move any motion so-called mechanical energy energy movement.
