Hello!
I need a help with one question:
Discuss weather any work is being done by each of the following agents, and if so, wether the work is positive of negative.
a) a chiken scratching the ground (what I think is that work is performed as
W=F∆x, and if the chicken moves her leg back and forth making ∆x equal to zero it means that there is no work done)
b) a person studying (the student does not move and does not have have any force it means that he does not make any work)
c) the leg muscles of a person in the act of sitting down (here I have not clue how to answer it)
Am I on the right way? And how to answer on the last question?
