Question

What is buoyancy and buoyant force?​

Answer 1

$\underline{\boxed{\tt{\huge{\green{Answer}}}}}$

Buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.

Answer 2

Explanation:

Buoyancy

Is the force that cause object to float it is the force exerted on an object that is party or wholly immersed in a fluid . Buoyancy is caused by the difference is pressure acting on opposite side of an object immersed in a static fluid

Buoyant

when an object is immersed in a liquid it experience on upward force know as Buoyant Force . this phenomenon of experiencing an upward force is known as Buoyancy

Remark

Force : Buoyancy is the Phenomenon due to Buoyant Force

For Example

A Submarine has a large ballast tank which is used to control it's position and depth from the surface of the sea

Remark point

A submarine submerge ballast that weight become greater than Buoyant Force

Some Application of Buoyant Force

• The Buoyant Force depend the volume of the body immersed which is equal to the volume of fluid displace
• The Density Of the Fluid

Some important Formula of Buoyant and

Buoyancy

Density = Mass / Volume

Relative Density

Density of a substance / Density of

water at 4°C
