  1. Buoyancy Important points to consider: • The weight of an object can be expressed as • If the object is fully submerged, V object = V Displaced Fluid

  2. The Problem: A downward force of 18 N must be applied to an object weighing 480 N to keep it fully submerged in water. Find the density of the object. + y F Buoy object F applied w object We want to just keep is submerged and not accelerate it upwards or downwards, so  F = 0. Draw a free-body diagram of the object.

  3. We can describe the buoyant force as:

  4. Because the object is fully submerged, this is also the volume of the object. So, we need a relationship between volume and density:
