Question

How do the units of work and power compare

Answer 1

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). ... Power may be measured in a unit called the horsepower.

Answer 2

Explanation:

Work - Work is the amount of energy which is transferred from a system by the force.

On the other hand, work is the product of the force and displacement. its unit is Nm or Joules.

Formula of the work

Work = Force X displacement

Work = unit of force X unit of displacement

`W = kg-m/s^(2)* m`

`W = Nm`

`W = Joules`

Power - Power is the work done per unit of time.

On the other hand, power is the work done divided by the time. its unit watt.

Formula of Power

Power = work/ time

Power = unit of work/unit of time

`P = (Joule)/(sec)`

`P = watt`

Hence, this is the required solution.
