Doing work vs work done
For w, when is it positive? Is it when work is being done on the system or when the work is being done by the system?

Re: Doing work vs work done
Work is positive when work is done on the system but it is negative when the system is doing work.
Re: Doing work vs work done
W is positive when work is being done ON the system and negative when the system is doing the work.

Re: Doing work vs work done
Work is positive when it is being done on the system (eg. compression) while work is negative the system is doing work on the system (eg expansion).

w is positive when work is done on the system and w is negative when the system does work.

W for the system is negative when the system does work. W for the system is positive if work is done on the system.

Doing work on the system results in a positive w value, whereas the system doing work results in a negative w value.
