Mechanical Properties of Fluids

In the NCERT Physics book Physics Part 2 (Class 11, Chapter – “Mechanical Properties of Fluids”), you explore how liquids and gases behave when forces act on them. You learn about fluid pressure and how it changes with depth in liquids.

You study important principles such as Pascal’s law and Archimedes’ principle, which explain how pressure is transmitted in fluids and why objects float or sink. The chapter also introduces concepts like surface tension and viscosity, which describe the internal behavior of fluids.

You also learn about Bernoulli’s principle and streamline flow, which help explain how fluids move in pipes, rivers, and even air around airplane wings. Through this chapter, you develop the ability to understand and analyze fluid behavior in both natural phenomena and technological applications.
