Up thrust and Archimedes' Principle

Up thrust and Archimedes' Principle

1. Buoyancy: The upward force experienced by a body when partially or wholly immersed in a fluid is called up thrust or buoyant force whereas the phenomenon responsible for this force is called Buoyancy

   • Up thrust
     • Up thrust =W {W=mg}
     • Weight of the fluid displaced by the immersed part of the body

2. Archimedes principle: When a body is partially or wholly immersed in a fluid, it experiences an untrustworthy, which is equal to the weight of the fluid displaced by the immersed part of the body.

3. RD: The ratio between density of a substance and density of water at 4*C

   • It has no unit
   • Density =R.D. X 1000
