In what direction does the buoyant force on an object immersed in a liquid act?

AcademicPhysicsNCERTClass 9


An object immersed in a liquid.

To do:

To state the direction of the buoyant force acting on the object immersed in the water.


When an object is immersed in a fluid such as water, two force acts on the object-

1. Buoyant force

2. Weight of the body

Let us discuss a little about the force acting on a body immersed in water and its directions-

1. Buoyant force:

When any object is immersed in a fluid, then a buoyant force is exerted by the liquid in a vertically upward direction to oppose the weight of the object. 

2. Weight of the body:

When an object is immersed in a fluid, it exerts its weight vertically in a downward direction. 

Direction of the buoyant force:

from the above discussion, we can conclude that the fluid exerts a buoyant force on the object vertically in an upward direction.
