This book is written for NET and GATE aspirants applying in Physics. Classical mechanics is an important branch to score marks. Questions asked frequently are mostly on the Lagrangian and Hamiltonian and deduction of equation of motion from these. The quantities remain conserved in motion are asked using Lagrangian and Hamiltonian formulation. Problems given are solved completely with interpretations and their importance in classical mechanics. Questions asked in last 10 years in CSIR-NET and GATE exams are solved.
