cavendish and he had kind of a neat way of doing it and someone shortly after that by the name of philip von jolly found an even simpler way to find what g is and here's what von jolly did. von jolly had a mass that was balanced with a known mass over here. underneath this mass, he rolled six tons of lead. and that's m2. and he knew this very, very accurately and he knew this very, very accurately. and when he did that, guess what happened, gang? this side pulled down a slight, slight bit. it got out of equilibrium. so what von jolly did was he put some other little masses on here, now he didn't have this equal like this, i mean, you can see the darn thing, okay? but he puts some other little masses there and restored the balance. when he put the other little masses here to restore the balance that's to say he has the force that pulled this down. he knows the force? he knows the mass? 1, he knows m 2 and he could measure the distance very accurately. he has everything except g. all you got to do is take that force, numerical value, divide it by the product of the masses, divided by the dista
