Question

What is buoyancy and buoyant force? On what factors do they depend?

Answer 1

1. Buoyancy: Buoyancy is the upward force exerted by a liquid on an object immersed in it. When you try to immerse an object in water, you will notice an upward force acting on the object, which will increase as you push it deeper into the water.

2. Applications of Buoyancy:

1. Swimming in Water
2. Flying a Bird

3. Factors on which Buoyancy depends:

The mass of the liquid displaced: The buoyant force is the upward force exerted on an item immersed in a fluid, whether completely or partially. Upthrust is another name for this upward force. A body submerged partially or totally in a fluid looks to shed weight i.e. appears to be lighter, due to the buoyant force.

Following are the factors that affect buoyant force:

1. The density of the fluid
2. The volume of the fluid displaced
3. The local acceleration due to gravity
