3 conditions under which work done becomes zero (with 1 example of each)
Answers
Explanation:
In physics, work done is actually always with the aspect of an external agent which is known to produce a force on some other entity. The work is stated as zero when there is no displacement of any given object along a line of force. So for example, if one would have a massive weight set of gym equipment and you are trying to lift it, but you are not able to do the same, here the work done by you would be zero because even though the effort or force is applied by you exists, there is no change in the location of the weight set.
Another example of zero work done in physics are:
Speaking about electrostatics, work done, is the product of charge and the potential difference. If the charge is moved along an equipotential surface, then the potential difference is known to be zero between the given two points.
