Work done is zero when a body moves up a hill or climb an object and then descend. In moving a body Q from point B to a point A along a path X, a work is done which is equal to the potential energy gained by the body. If the body then goes back from A to B along a path Y, it loses the potential energy gained and so the total work done on the body becomes zero.
Work is done when a force is applied to an object which moves in the direction of the force.
work is only said to be done when force applied to a load moves through a distance.that is to say that a man standing one place carry a load without moving for 5 hours have not done any work.
There are different conventions as to what work is negative and what work is positive. The convention used by engineers and physicists is that work done BY the system on its surroundings is positive while work done ON the system by its surroundings is negative. Chemists reverse these conventions.
No, HEAT is work done!
work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........
that there is a wor done
that there is a wor done
that there is a wor done
when a force acts to move an object,we say that work was done on the object

Negative work
asses u supposed to know that
When you expend the energy to complete that project.

You can say "ka pai, tino pai te mahi" in Maori to mean "well done, great work."
Well there will probably be a variety of answers, depending on how you mean it. If you say "Good Work" as a praisal of some good work done, you just say "Godt arbejde". It is just the literally translation actually.
