In physics work is dome when a force acts on a body and the body moves in the direction of the force.
force is present when work is done.
Work can be completed in three different situations: when force is present, when force is applied to a particular object, and when the force applied occurs in a parallel motion.

work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........

The way present perfect is formed is -- have/has + past participle.So the verb do would not be used in present perfect, but the past participle done is used.I have done my home work. = a positive sentence.I have not done my homework = a negative sentence.She has not done her homework. = negative sentence.The 'not' comes between the auxiliary verb have/has and the past participle.
The present perfect of do is have / has done.I have done my assignment. She has done her assignment too.
Have done is the present perfect tense. The simple present tense is do.For example:I have done my homework becomes I do my homework.You could also switch to the present continuous tense:I have done my homework becomes I am doing my homework.Or the present perfect continuous tense:I have done my homework becomes I have been doing my homework.
Well. Work is being done. While sitting down, the person does not apply any force. He lets himself be dragged down by gravity. During this process, the gravitational force is doing the work. The work done by the gravitational force is stored as the potential energy present in the compressed cushion.
Congress must have a 'quorum'. That means that at least half of the members must be present. That would be 50 in the Senate and 219 in the House.

Work can be completed in three different situations: when force is present, when force is applied to a particular object, and when the force applied occurs in a parallel motion.
