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. In mechanics, the … See more In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called … See more The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and … See more Power is related to intensity at a radius $${\displaystyle r}$$; the power emitted by a source can be written as: See more Power is the rate with respect to time at which work is done; it is the time derivative of work: If a constant force F is applied throughout a distance x, the work done is defined as $${\displaystyle W=\mathbf {F} \cdot \mathbf {x} }$$. … See more As a simple example, burning one kilogram of coal releases much more energy than detonating a kilogram of TNT, but because the TNT reaction releases energy much more … See more • Simple machines • Orders of magnitude (power) • Pulsed power See more WebJan 2, 2015 · If you consider the derivative with respect to time, it is the power, by definition: P = dW dt If you consider the derivative of the work with respect to position, we have the following result, using the Fundamental Theorem of Calculus: dW dx = d dx ∫ x a F (x′)dx′ = F (x) Which is the force.
WebNov 26, 2007 · A derivative is a rate of change, which, geometrically, is the slope of a graph. In physics, velocity is the rate of change of position, so mathematically velocity is the derivative of position. Acceleration is the … WebTime-derivatives of position In physics, the fourth, fifth and sixth derivatives of position are defined as derivatives of the position vector with respect to time – with the first, second, and third derivatives being velocity, acceleration, and jerk, respectively.
WebPower is the rate at which work is done. It is the work/time ratio. Mathematically, it is computed using the following equation. Power = Work / time or P = W / t The standard metric unit of power is the Watt. As is … WebJul 24, 2024 · Power = q E →. v → n d V. But the current density, J →, is a vector of magnitude equal to the charge per unit area crossing a small imaginary surface per unit time and direction that in which the charges are moving. It follows from this that J → = n q v →. Therefore Power = E →. J → d V.
