Question

different between centre of buoyancy ,centre of gravity, centre of mass , fast

Answer 1

centre of buoyancy :


it is the point through which the resultant of the buoyancy Force on a submerged body act ,is concerned with the centre of gravity of the displaced fluid. .


centre of gravity :



it is the point through which the weight of the body acts it is a point where the whole of the weight of the body may be supposed to be concentrated .



centre of mass :


for any system it is the point at which the whole of the mass of the body for system may be considered to be getting for determining the effect of some external force .

Answer 2

The center of gravity is the centroid of the mass of the object. The center of buoyancy is the centroid of the volume of water it displaces. They can be in the same location, but this is generally not a good idea. Centre of buoyancy is the centre of gravity of displaced liquid.

The center of mass is the mean position of the mass in an object. Then there's the center of gravity, which is the point where gravity appears to act. For many objects, these two points are in exactly the same place. But they're only the same when the gravitational field is uniform across an object.
