what is buoyancy define and explain in brief
Answers
Answer:
What is Buoyancy?
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.
We can define Buoyancy as:
The upward force applied by the fluid on the object or the body when an object is put in or submerged in the fluid.
Unit:
The unit of the buoyant force is the Newton (N).

Explanation :
We can say, when immersed in water or any other fluid, the body experiences a force from the downward direction opposite to the direction of the gravitational pull, which is responsible for the decrease in its weight. It can be the reason why a ball of plastic floats in water rather than sinking to the base by its weight. But here too, we observe that some objects such as a plastic bottle float over water, while others such as a needle sink. In this article, we shall learn about the concept of buoyancy and buoyant force which gives a proper explanation of such observations.
