Power

Flashcards covering the concept of power, its definitions, calculations, and related terms.

Power

The rate at which work is done by a force.

Average Power

Calculated using the formula $P_{avg} = \frac{W}{\Delta t}$.

Instantaneous Power

Defined as $P = F \cdot v$, the product of force and velocity.

Units of Power

Expressed in joules per second (Js$^{-1}$) or watts (W).

Work Done by Force

When a particle moves under the influence of a constant force at an angle $\phi$, the work is calculated as $d = F \cos \phi \cdot d$.

Direction of Force

In the context of power, the force is directed at some angle $\phi$ to the x-axis.
