This textbook has been conceptualised to meet the needs of B. Sc. First Semester students of Physics as per Common Minimum Syllabus prescribed for all Uttar Pradesh State Universities and Colleges under the recommended National Education Policy 2020. Designed strictly as per the syllabus, the first part of the textbook comprehensively covers the theory paper, Mathematical Physics & Newtonian Mechanics, which discusses important topics such as Newton's axioms of motion, dynamics of particles, pseudo forces and the mathematical base including tensors. The second part of the textbook systematically covers the practical paper, Mechanical Properties of Matter, to help students achieve solid conceptual understanding and learn experimental procedures. Well drawn illustrations and examples have been provided not only to substantiate the basic principles involved but also to make reading interesting and engaging Includes apt number of solved/unsolved numerical problems, frequently asked in various university examinations, for students' practice Evaluate Yourself feature at the end of each chapter provides short/long answer questions to test students' understanding of the concepts Paper I: MATHEMATICAL PHYSICS AND NEWTONIAN MECHANICS Z: Contribution of Ancient Physicists in the Development of Modern Science and Technology 1: Vector Algebra 2: Vector Calculus 3: Coordinate Systems 4: Introduction to Tensor 5: Dynamics of a System Particles 6: Dynamics of a Rigid Body 7: Motion of Planets and Satellites 8: Wave Motion PAPER II: MECHANICAL PROPERTIES OF MATTER Z: First Step in Laboratory 1: Moment of Inertia of a Flywheel 2: Moment of Inertia of an Irregular Body by Inertia Table 3: Modulus of Rigidity by Statical Method (Barton's Apparatus) 4: Modulus of Rigidity by Dynamical Method by Maxwell Needle Method 5: Young's Modulus by Bending of Beam 6: Young's Modulus and Poisson's Ratio by Searle's Method 7: Poisson's Ratio of Rubber by Rubber Tubing 8: Surface Tension of Water by Capillary Rise Method 9: Surface Tension of Water by Jaeger's Method 10: Coefficient of Viscosity by Poiseuille's Method 11: Acceleration Due to Gravity 12: Frequency of AC Mains by Sonometer 13: Height of a Building by Sextant 14: Study the Waveform of a Alternating Current Source with the Help if Cathode Ray Oscilloscope
