In economics, a measure of productive efficiency calculated as the ratio of what is produced to what is required to produce it.\nAny of the traditional factors of production\nland, labour, or capital can be used as the denominator of the ratio, though productivity calculations are actually seldom made for land or capital since their capacity is difficult to measure. Labour is in most cases easily quantified\nfor example, by counting workers engaged on a particular product. In industrialized nations, the effects of increasing productivity are most apparent in the use of labour. Productivity can be seen not only as a measure of efficiency but also as an indicator of economic development. Productivity increases as a primitive extractive economy develops into a technologically sophisticated one. The pattern of increase typically exhibits long-term stability interrupted by sudden leaps that represent major technological advances. Productivity in Europe and the U.S. made great strides following the development of such technologies as steam power, the railroad, and the gasoline motor. Later in the 20th century, advances in productivity stemmed from a number of innovations, including assembly lines and automation, computer-integrated manufacturing, database management systems, just-in-time manufacturing, and just-in-time inventory management. Increases in productivity have tended to lead to long-term increases in real wages.

It is the energy emitted per unit time; the power. \n\nTherefore, its dimensional formula is Mass x Length^2 / Time^3.\n\nOr ML^2T^(-3).

It is the SI unit of energy. It is also the unit for work in physics (force times distance). But I don't get the rest of your question.

A voltmeter and an ammeter will provide the input power. You will need some form of dynamometer to measure output power.\n\nOutput power divided by input power yields efficiency.

Ya Time is just a measure of change... If there is change then you can say that there is time... No-time isn't a "theory" it's an idea, a thought game.

Time is a human creation used to put a measurable scale to the sequence of events that happen in the universe.

Productivity is measured or computed based on resources, manpower-time required and how much product is being produced. Productivity is essentially how much of product is being made per amount labor spent.\n\nThe equation I would use is\n(Quantity of product) / (Cost of resources + cost of labor) assuming that the cost per unit is the same we have.\n\nForest 4.7/ (7.5+6.2) = .34\nVillage 3/(7.2 + 5.6) = .23\n\nThe higher the number of items produced  (antelopes in this case) the more productive is the group so forest is more productive.

With advances in relativity, quantum mechanics and microscopy, time is actually currently defined as measuring the number of vibrations of a cesium atom.\n\nSince this motion slows down as you approach the speed of light, it could be said that we are measuring how much matter/energy has slowed down from the speed of light since the big bang...\n\nSince entropy is defined as, "the amount of energy that cannot be used to do work," measuring how long it has been since the big bang is not QUITE the same as measuring the amount of energy that cannot be used to do work.\n\nFor example, entropy itself has changes as our technology has progressed - we are now able to utilize a larger percentage of wind and solar energy than ever before in history, which necessarily means that the rate that entropy is increasing has slowed.  There is no reason to believe this will not be the case in other areas, such as nuclear fusion (which powers stars) or even tapping the vast vaccuum energy that is omniprescent throughout space.\n\n:)

Electric power has two components:\n\nActive power, which produces work.\nReactive power, which is needed to generate magnetic fields required for operation of inductive electrical equipment, but performs no useful work. \nActive power is measured in KW (1000 Watts) \nReactive power is measured in KVAR (1000 Volt-Amperes Reactive) \nTotal power is measured in KVA (1000 Volt-Amperes)\n\nPower Factor is the measure of the relationship between Active and Reactive power at the point of consumption.\n\ncheck out powerfactorhelp.com -- pretty clear and simplistic

There is no such thing.\n\nCurrent is current, measured in amperes. Watts are power.\n\nPower is a measure of work per unit time. One watt (of power) is one joule (of work) per second.\n\nOne ampere (of current) is one Coulomb (of electrical charge) per second.\n\nIt takes one joule of work to push one Coulomb of charge through one volt.\n\nAnd finally, a watt-hour is an amount of work--the power of one watt for one hour. It is 3600 joules.

Coolfrendz!, You have coolly omitted accelaration due to gravity.\nDemolisher!, You have demolished the time factor.\n\nPower is the work done per unit time.\nWork is force times displacement. (Distance moved along the direction of the force)\nForce is mass times the acceleration.\nIn the problem, \nThe force acting on the man is mass of the man x acceleration due to gravity. \nThe displacement is the vertical height of the hill.\nThe work done is mass of the man x acceleration due to gravity  x  vertical height\nThe power is mass of the man x acceleration due to gravity  x  vertical height  divided by time.

Horsepower is simply a unit used to measure power (in English or standard units, for comparison the metric unit is a Watt).  Power is defined as change in energy over change in time (in the same way that a slope is defined as change in height over change in distance).  So two equivalent cars, differing only in the amount of horsepower that they produce, can change their energy faster (i.e. more power=more energy change/same time or =same energy change/shorter time).  The horsepower given in the commercials only refers to the engines, (it could also apply to the brakes!)so the energy we're talking about here is the energy of movement or kinetic energy.  To make a short story long, a vehicle with more horsepower will be able to speed up faster than the same car with less horsepower.

I suppose the power is inversely proportional to the square of the distance. Thus a square meter on Pluto gets 1/1600 as much power as one on Earth, or 1400/1600, 7/8 of a watt.

By definition, a watt is "the SI unit of power. Power is the rate at which work is done, or (equivalently) the rate at which energy is expended."\n\nA 50-watt bulb is expending energy at 1/2 the rate of a 100-watt bulb.\n\nSo - if both are shining (not "shinning") for the same amount of time, the 50-watt bulb would use 1/2 the energy of the 100-watt bulb.
