If a is zero, if the objects just sitting there, that's called neutral buoyancy, then we need Roe v G to be equal to M. G. Remember, this is the density of the liquid. The volume of the object in the mass of the object G can cancel, which means we need the density of the liquid to be equal to the density of the object. About This Quiz & Worksheet.

Textbook Readings. ScienceFocus 8 Pages 64 & 65 or Science in Action 8 Page s 50 & 51. Buoyancy is a force that works opposite to gravity. You may have experienced the effect of buoyancy when you climb out of a swimming pool. Buoyancy Buoyancy causes things to be pushed in the opposite direction to gravity. This happens when they are less dense than the fluid they are in, like an apple in water, or a helium balloon in air (yes, technically air is a fluid :) The strength of the buoyancy force depends on the mass of fluid displaced.
