Objective: This course has been so framed that the students are first exposed to the mathematical tools needed in Mechanics and Special Relativity. Students are then taught the topics of conservation laws, elastic and inelastic scattering, dynamics of rigid bodies and inverse-square law of forces in the framework of Newtonian Mechanics.
Fundamentals of dynamics: Motion of Charged particles in electric and magnetic fields.Dynamics of a system of particles. Centre of mass. Conservation of momentary. Idea of conservation of momentum from Newton’s third law. impulse. Momentum of variable mass system: motion of rocket, work-energy theorem. Potential energy. Energy diagram. Stable and unstable equilibrium. Conservative and non-conservative forces. Force as gradient of potential energy. Particle collisions. Centre of mass frame and laboratory frame
Conservation Laws: Conservation of Energy, Conservative forces, Internal forces and conservation of linear momentum, Centre of mass, systems with variable mass, Space-Vehicle Problem. Conservation of Angular Momentum, Internal torques, Angular Momentum about the Centre of mass, Rotational invariance, Shape of Galaxy. (Chs. V and VI of Book 2, Ch. 5 of Book 3).
Elastic and Inelastic Scattering : Types of scattering and conservation laws, Laboratory and centre of mass systems, collision of particles which stick together, General elastic collision of particles of different mass, Cross-section of elastic scattering, Rutherford scattering. (Ch. VI of Book 1, Ch. 7 of Book 2).
Dynamics of Rigid Bodies : Equation of motion, angular momentum and kinetic energy of a Rotating Body, Moment of Inertia and Radius of Gyration, Rotation of about fixed axes – time dependence of motion, cylinder on an accelerated rough plane, Behaviour of angular momentum vector, Principal axes and Euler’s equations. Elementary Gyroscope, Symmetrical Top. (Ch.VIII of Book 2, Ch. 8 of Book 3).
