What is meant by buoyant force?

Dear Student,

• Buoyant Force:
When a body is partially or wholly immersed in a fluid, it displaces the fluid. The displaced fluid has a tendency to regain its original position . Due to which an upward force is exerted on the body which is called the buoyant force.

• Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.

• Buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object.

• Acceleration is defined as the rate of change of velocity with respect to time.

• Buoyant force, If the buoyant force is less than the object's weight, the object will sink. If the buoyant force equals the object's weight, the object will remain suspended at that depth, and if the buoyant force is greater than the object's weight, the object will rise to the surface and float.

Buoyancy is the force that causes objects to float. It is the force exerted on an object that is partly or wholly immersed in a fluid. Buoyancy is caused by the differences in pressure acting on opposite sides of an object immersed in a static fluid. It is also known as the buoyant force. Buoyancy is the phenomena due to Buoyant Force.

The unit of the buoyant force is the Newton (N).

When a body is in water, it displaces some amount of water owing to its weight. The amount of displaced water is computed by the object’s density which relates to volume. The volume of a cricket ball and beach ball can be the same as their different weight their density differs. The solid steel block descends in water but the steel ship does not. Therefore, the quantity of displaced water in the upward direction is elucidated in terms of Buoyant force. Let’s discuss the buoyancy force and its formulation with diverse devices grounded on it.

When an object is immersed in a liquid it experiences an upward force known as Buoyant Force. This phenomenon of experiencing an upward force is known as Buoyancy.

It is as an upward force exerted by a fluid that opposes the weight of an object immersed in a fluid. As we know, the pressure in a fluid column increases with depth. Thus, the pressure at the bottom of an object submerged in the fluid is greater than that at the top. The difference in this pressure results in a net upward force on the object which we define as buoyancy
