Special Theory of Relativity
Free PDF Notes — CSIR NET · IIT JAM · GATE
4 complete chapters — Lorentz Transformation, Mass-Energy Equivalence, Relativistic Four-Vectors, and Relativistic Electrodynamics. 13 PDF files covering the entire Special Relativity syllabus for CSIR NET, IIT JAM, GATE, JEST, and TIFR. 100% free, no login required.
Chapter 1: Lorentz Transformation
6 PDFsMichelson-Morley experiment, Galilean and Lorentz transformations, relative velocity addition, length contraction, time dilation, and loss of simultaneity. The foundational chapter of Special Relativity tested in every CSIR NET and IIT JAM paper.
Chapter 2: Mass-Energy Equivalence
2 PDFsRelativistic mass derivation, rest mass energy, Einstein’s E=mc², energy-momentum relationship, relativistic kinetic energy, relativistic force and Newton’s laws in 1D, and relativistic momentum.
Chapter 3: Relativistic Four-Vectors
3 PDFsSpace-time unification, space-like, time-like and light-like intervals, Minkowski diagrams, symmetry in energy and momentum, relativistic Doppler effect (longitudinal), four-vector properties, inner product invariance, and relativistic collisions and decays.
Chapter 4: Relativistic Electrodynamics
2 PDFsFour-current vectors and their transformation properties. Transformation of electric and magnetic fields under Lorentz boosts. Connects Special Relativity directly to Electrodynamics — a high-value topic for CSIR NET Part C and GATE Physics.
Special Theory of Relativity for CSIR NET, IIT JAM and GATE Physics
The Special Theory of Relativity is a compact but high-value topic across all major physics competitive examinations. In CSIR NET Physical Sciences, it features consistently in Part B and Part C, testing Lorentz transformations, relativistic kinematics, and four-vector formalism at advanced levels. In IIT JAM Physics, Special Relativity contributes 5-10% of marks, with problems on time dilation, length contraction, and relativistic energy-momentum. For GATE Physics and JEST/TIFR, it is a reliable and high-scoring topic that rewards students who master the four-vector framework.
Pravegaa Education’s free Special Theory of Relativity PDFs are organized in a clean four-chapter structure that takes the student from the historical Michelson-Morley experiment through the full four-vector and relativistic electrodynamics framework. Every chapter is written for exam-depth conceptual clarity, not just formula memorization.
Chapter Priority for CSIR NET
- Chapter 3 — Four-Vectors and Minkowski Diagrams: Spacetime intervals, relativistic invariants, and collision problems are the most frequently tested STR topics in CSIR NET Part C.
- Chapter 4 — Relativistic Electrodynamics: Transformation of E and B fields under Lorentz boosts appears regularly in CSIR NET Part C, especially in combined EM-Relativity problems.
- Chapter 2 — Mass-Energy Equivalence: Relativistic energy-momentum relation E² = (pc)² + (m₀c²)² is tested both conceptually and numerically.
Chapter Priority for IIT JAM Physics
- Chapter 1 — Lorentz Transformation: Time dilation and length contraction numerical problems appear in almost every IIT JAM paper.
- Chapter 2 — Mass-Energy Equivalence: E=mc² applications, relativistic kinetic energy, and momentum problems are standard IIT JAM questions.
- Chapter 3 — Relativistic Doppler Effect: Longitudinal Doppler shift problems appear in IIT JAM Modern Physics section.
