Buoyancy
→ The upward force experienced by an object when it is immersed into a fluid is called force of
buoyancy.
→ It acts in upward direction and it depends on the density of the fluid.
→ When force of gravitational attraction of the earth on the surface of the object < buoyant force
exerted by fluid on the surface of the object, object floats in the fluid.
• When force of gravitational attraction of the earth on the surface of the object > buoyant force
exerted by fluid on the surface of the object, the object sinks in the fluid.
→ This is the reason, why allpin sinks and boat/ship floats on the surface of water. (Archimedes
principle)
