This text is designed to meet the requirements of undergraduate physics students. The book is divided into four units and nine chapters dealing with the basic concepts of mechanics and wave motion. The first three units cover topics related to mechanics, the fourth unit covers topics related to wave motion. Coverage is systematic, logical and includes solved examples. Short and long answer type questions, unsolved numerical and multiple-choice questions are provided at the end of each chapter. Broadly it includes:* The laws of motion and inertial frames.* Conservation laws.* The dynamics of rigid bodies.* Elasticity.* Gravitation.* Simple harmonic motion.* Damped harmonic oscillator.* Forced harmonic oscillator.* Wave motion.
