JEE Main Physics: Fluid Mechanics – Properties, Principles & Applications

Fluid Mechanics is the branch of Physics that deals with the behavior of liquids and gases at rest and in motion. It is an important topic in JEE Main Physics and helps students understand how fluids flow and exert pressure.

What is Fluid Mechanics?

A fluid is a substance that can flow and take the shape of its container. Fluid Mechanics studies the properties of fluids and the forces acting on them under different conditions.

Characteristics of Fluids

Fluids can flow easily.
They do not have a fixed shape.
They exert pressure in all directions.
Their behavior depends on factors such as density and viscosity.
