The work being done will be increased if you pick it up instead of dragging it due to the friction.
Work is force times displacement (distance). Thus, about 3 work is being done. The unit depends on the unit of the work and distance. If the work unit is Joules, and the distance unit is meters, then the force unit would be Newtons.
Instead work on object, work is being done by the object during its free falling
Yes Please
Work is the word used to describe anything that's being physically done whereas energy is what is needed for work to be done. So in a simple form - You need energy to work.
work is being done when you use energy
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
work can only be done by a living being
It is work that is being done in a laboratory.
Yes it is.
you know when work is done when it's finished and checked and approved by someone.
Yes it is being done, if the person doing it is doing it as part of a paid job or because they run a business and the letter is needed for the business. If it is being typed for school it may also be considered work, but of a different kind. And from the view of physics, since energy is being expended by the person typing, and perhaps by the machinery being used, work is being done. However, if you are at work and typing a letter to your grandmother, that is not the kind of work you are being paid for and your employer would say work is not being done.
you apply a force to an object
The work being done will be increased if you pick it up instead of dragging it due to the friction.
Of corse,potential energy of pencil is increased.Therefor work done
Moved. Work is defined as a force acting on an object through a distance.
The opposite activity of work can be "play." The opposite of work being done is work not being done, as in sloth, idling, or relaxation. The opposite of work (having a job) is "unemployment." Other possibilities: idleness, stasis, or rest.
