Question

The time rate at which work is done by a force is

Answer 1

Power:

1. Power can be defined as the rate at which work is done.
2. Power is denoted by the alphabet “P”.
3. The SI unit of power is the $\mathrm{watt}\left(\mathrm{W}\right)$.
4. Power is a scalar quantity.

Mathematically, power can be represented as:

$\mathrm{P}=\frac{\mathrm{W}}{\mathrm{t}}$

Here,

W is the work done.

t is the time taken.

Therefore, the time rate at which work is done by a force is power.
