Work (physics) - Wikipedia
WEBThus, at any instant, the rate of the work done by a force (measured in joules/second, or watts) is the scalar product of the force (a vector), and the velocity vector of the point of application. This scalar product of force and velocity is known as instantaneous power .
9.1 Work, Power, and the Work–Energy Theorem - Physics
WEBPower is the rate at which work is done. In this case, rate means per unit of time . Power is calculated by dividing the work done by the time it took to do the work.
Power - The Physics Classroom
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 implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time.
7.2: Work - Physics LibreTexts
WEBSep 12, 2022 — Evaluate the work done for various forces. In physics, work represents a type of energy. Work is done when a force acts on something that undergoes a displacement from one position to another. Forces can vary as a function of position, and displacements can be along various paths between two points.
Work, Energy and Power - HyperPhysics
WEBThe rate of doing work is equal to the rate of using energy since the force transfers one unit of energy when it does one unit of work. A horsepower is equal to 550 ft lb/s, and a kilowatt is 1000 watts.
Work, Energy and Power - Definition, Examples, Formula, Units
WEBAs discussed, power is the rate of doing work. Therefore, it can be calculated by dividing work done by time. The formula for power is given below. \ (\begin {array} {l}P = \frac {W} {t}\end {array} \) Where, P is the power, W is the work done and t is the time taken.
7.4 Power - University Physics Volume 1 - OpenStax
WEBWe express the relation between work done and the time interval involved in doing it, by introducing the concept of power. Since work can vary as a function of time, we first define average power as the work done during a time interval, divided by the interval,
7.1 Work - University Physics Volume 1 - OpenStax
WEBIn physics, work is done on an object when energy is transferred to the object. In other words, work is done when a force acts on something that undergoes a displacement from one position to another. Forces can vary as a function of position, and displacements can be along various paths between two points.

6.6: Power - Physics LibreTexts
WEBIn physics, power is the rate of doing work. It is the amount of energy consumed per unit time. The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine).
