What is buoyancy and buoyant force?
Answers
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.
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
