Introduction
Physics in JEE is all about concepts and formulas. A strong grip on formulas helps you solve problems quickly and accurately. This guide provides a quick revision of important formulas across major topics. Regular revision can significantly boost your performance.
Mechanics Formulas
- Velocity: v = u + at
- Displacement: s = ut + ½at²
- Force: F = ma
- Work: W = Fs cosθ
- Kinetic Energy: KE = ½mv²
Thermodynamics Formulas
- First Law: ΔQ = ΔU + W
- Work Done: W = PΔV
- Ideal Gas Equation: PV = nRT
- Efficiency: η = Work Output / Heat Input
Electrodynamics Formulas
- Ohm’s Law: V = IR
- Electric Force: F = kq₁q₂ / r²
- Electric Field: E = F/q
- Power: P = VI
Modern Physics Formulas
- Photon Energy: E = hν
- De Broglie Wavelength: λ = h/p
- Einstein Equation: E = mc²
How to Revise Effectively
- Daily Revision: Spend 30 minutes revising formulas
- Short Notes: Maintain a formula notebook
