Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work.
Definición. La potencia es la relación con respecto al tiempo a la que se realiza el trabajo; es la derivada temporal del trabajo: donde P es la potencia, W es el trabajo y t es el tiempo. Si se aplica una fuerza constante F a lo largo de una distancia x, el trabajo realizado se define como En este caso, la potencia puede escribirse como:
In physics, power (symbol: P) is how fast work is done or energy is given from one thing to another. In the SI system of measurement, power is measured in watts (symbol: W). It may take a certain amount of work to make a change in the world, such as lifting a heavy weight to a higher level.
Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
Electric power. Electric power is transmitted by overhead lines like these, and also through underground high-voltage cables. Electric power is the rate of transfer of electrical energy within a circuit. Its SI unit is the watt, the general unit of power, defined as one joule per second.
Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is ...
19 de jul. de 1998 · Power, in science and engineering, time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t—or W/t. A given amount of work can be done by a low-powered motor in a long time or by a high-powered motor in a short.
