Doing work vs work done

Postby vanessas0123 » Sun Mar 15, 2020 8:32 pm

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?

Work is positive when work is done on the system but it is negative when the system is doing work.

W is positive when work is being done ON the system and negative when the system is doing the work.

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.
