Buoyancy (/ˈbɔɪənsi, ˈbuːjənsi/), 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.
Answers & Comments
Answer:
✩ When an object is kept in a fluid, it experiences
an upward force.
✩ Substances thus appears lighter when immersed
completely or partially in a liquid.
✩ The tendancy of a fluid to exert an upward force
on the object wholly or partially immersed in a
it is called buoyancy.
✩ The upward force that acts on the object imersed
in a fluid is called buoyancy force.
