Starkstrom (Maskulin)

Description: Power is the Work $\Delta W$ and/or energy $\Delta E$ that is implemented over a specific period of time $\Delta t$. Power P is measured in $Nm/s$ or W (watts). It is important in both Mechanics and as electrical power. It is calculated using the formula $P(t)=\frac{\Delta W}{\Delta t}$ or $P(t)=\frac{dW}{dt}$. In the case of a translational movement, power P is the product of the Force vector $\overrightarrow{F}$ and the Velocity vector $\overrightarrow{v}$ that is acting in the same direction. In the case of a Rotation, it is the product of angular velocity $\overrightarrow{\omega }$ and moment $\overrightarrow{M}$. In hydraulics, power is obtained by multiplying the volumetric flow rate Q by pressure p.
