If the buoyant force of a fluid is greater than the downward ... But objects that are more dense than water (at the surface) will sink until the forces are equalized. Ships, you may have noticed ...

There are two forces acting on the life jacket - its weight and the force of the water pushing upwards on ... Things that float are buoyant. If the weight is greater than the upthrust, it sinks.

The difference between the ‘pulling' and ‘pushing' forces is proportional to the buoyancy. Air that rises far enough will experience condensation of water vapor into a cloud, which further ...
