Hi,(adsbygoogle = window.adsbygoogle || []).push({});

When you hang a mass on a pulley and allow the mass to fall, do you normally have to take into account the work due to tension in the equation U1 + K1 - W(tension) = U2 + K2???

I laways thought you did, but it doesn't take W(tension) into account in one of my problems.

Thanks so much.
