Re: Physics definition of work



So, does this mean the expectations have definitely been switched for the
AP?

explained.

In one of their "pieces" their new AP exams were being described and it
stated that (something to the effect);

"we are now going to use the new definition of physics work where we
measure work done "on" the system rather than work done "by" the system.
The result is to have all plus signs in the First Law of Thermo -- just as
chemistry does it."
