When does a force do work

Asked by Manjokumargupta8084 | 31st Jul, 2018, 04:42: PM

Expert Answer:

Work is said to be done when force is applied on a body which results in it's displacement.
However, if a force is applied perpendicularly on a body, it may not move.
Therefore, it can be said that a force will not do a work when it is applied perpendicularly and if it is applied along the direction of displacement, the force will result into work.
