Aperson struggles very hard to lift a large boulder. he puts in so much effort, he starts to sweat, his heart rate increases, and he gets really tired. all of his effort is for nothing, the boulder does not move at all. in this situation, has work been done? explain! *use the scientific definition of "work" to answer this question.

No, according to physics no work has been done.

Work must have been done by muscular force but in terms of physics no work has been done.

In physics,work is said to be done only if the force applied produced some kind of displacement in the direction of force.

In this example provided, no work has been done since the boulder doesn't get displaced,it continues to remain at its original position.
