Chapter 10, Problem 35A

To determine

The units in which the work is measured.

Explanation of Solution

Introduction:

When a force is applied on an object and the object moves, it is said that work is done.

Mathematically,

  $W=Fd\cos \theta$

Where, $F$ is the applied force $d$ is the displacement and $\theta$ is the angle between force and displacement.

The SI unit of work is N-m (newton-meter) and is also written as Joule (J).

The CGS unit of work is dyne-cm called as Erg.

Some other used units of work are kilowatt-hour, horsepower-hour, liter-atmosphere, BTU, calorie, etc.
