Properties of Solids and Liquids

Properties of Solids and Liquids is an important chapter in JEE Main Physics. It covers elasticity, stress, strain, fluid pressure, viscosity, surface tension, capillary action, and fluid dynamics. This chapter combines theoretical concepts with formula-based numerical problems.

Topics Covered

• Elastic Behavior of Solids
• Stress and Strain
• Hooke’s Law
• Young’s Modulus
• Bulk Modulus
• Shear Modulus
• Pressure in Fluids
• Pascal’s Law
• Archimedes’ Principle
• Surface Tension
• Capillary Rise
• Viscosity
• Stokes’ Law
• Bernoulli’s Principle
• Equation of Continuity

Important Formulas

Stress:
Stress = Force / Area

Strain:
Strain = Change in Dimension / Original Dimension

Young’s Modulus:
Y = Stress / Strain

Pressure in Liquid:
P = hρg

Surface Energy:
E = T × A

Stokes’ Law:
F = 6πηrv

Equation of Continuity:
A₁V₁ = A₂V₂

JEE Main Preparation Tips
