    If we combine the downward force of gravity with the upward buoyant force, we get what is known as the apparent weight of the object, Wapparent = mobject9 – Fbuoyant = PobjectgVtotal – Poutside gVdisplaced · For our experiment this week, we will be looking at a mass submerged in water. The apparent weight will be the weight force due to gravity minus the buoyant force due to the surrounding water. Consider the setup to the right with an object...

    3. Archimedes' Principle states that the buoyant force on an object partially or fully submerged in a fluid is equal to the weight of the fluid that the object displaces. For an object of density po floating partly submerged in a fluid of density pf, the buoyant force is given by F P19 SA(y)dy, where g is the acceleration due to gravity and A(y) is the area of a typical cross-section of the object. The weight of the object is...
