| Abstract: | Principle of Archimedes is important way to compute buoyancy of object in the fluid.In gravitational field,we use basics principle of fluid statics,analyze buoyancy of object in the invariant density and static fluid,and obtain buoyancy of object in three different condition.It is indication that,we obtain buoyancy of object in three different condition agree with principle of Archimedes.In the process of calculation and discussion,we can understand the essence of buoyancy. |
