Question

Match the following physical quantities with their corresponding definitions/relations.

List - I	List - II
(P) Instantaneous Power	(1) Watt
(Q) Average Power	(2) $\frac{Δ W}{Δ t}$
(R) Unit of Power	(3) $F \cdot v$
(S) Power in terms of force and velocity	(4) $\frac{d W}{d t}$

TestHub · Accepted Answer

Instantaneous power is the derivative of work with respect to time, P = d W / d t . Average power is the total work done divided by the total time taken, P a vg ​ = Δ W /Δ t . The SI unit of power is Watt. Power can also be expressed as the dot product of force and velocity, P = F ⋅ v .
