Archimedes Principle - Class 9 Tutorial

Archimedes Principle states that the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object.

Through the video, we can learn:

1. When a body is partly or completely immersed in water, it loses weight.
2. A body loses its maximum weight when it is completely immersed in water.
3. When a body is partly or completely in water then:

Loss in weight of the body = Weight of water displaced by the body = Buoyant Force or up-thrust exerted by water on the body.

Volume of the water displaced = Volume of the body immersed in water.
