Work is said to be done whenever a load moves through a distance. i.e. work = force × distance moved in the direction of the force (f × d).</p> <p><br>Work involves applying force over a certain known distance. Work is therefore a product of force and the distance through which the force is applied. The unit of energy and work is known as Joules (j). A joule is the work done when a force of one (1) newton moves through a distance of one (1) metre.</p> <p><br>Example 1: If the mass of a block is 5kg, the work done by the block in moving up through 0.3m is given by: <div class="sign-up-notice-after-excerpt-two" style="background-color:powderblue;"> You are viewing an excerpt of this lesson.
