Archimedes Lab

I am concerned that many of you will soon, if not already, confuse the reading of the scale with the object submerged with the mass of the beaker+ mass water + mass of object. This is NOT the case.

the reading of the scale with the object submerged IS the mass of the beaker+ mass water + the force of the object on the water. This last quantity, the force of the object on the water, is the buoyant force.(except it's down where Fb is up)
