1 VITEEE – 2020 – PHYSICS 1. Laws of Motion & Work, Energy and Power Law of conservation of linear momentum and its applications. Static and kinetic friction - laws of friction - rolling friction - lubrication. Work done by a constant force and a variable force; kinetic energy - work-energy theorem - power. Conservative forces: conservation of mechanical energy (kinetic and potential energies) - non-conservative forces: motion in a vertical circle - elastic and inelastic collisions in one and two dimensions. 2. Properties of Matter Elastic behaviour - Stress-strain relationship - Hooke's law - Young's modulus - bulk modulus - shear modulus of rigidity - Poisson's ratio - elastic energy. Viscosity - Stokes' law - terminal velocity - streamline and turbulent flow - critical velocity. Bernoulli's theorem and its applications. Heat - temperature - thermal expansion: thermal expansion of solids - specific heat capacity: Cp, Cv - latent heat capacity. Qualitative ideas of Blackbody radiation: Wein's displacement Law - Stefan's law. 3. Electrostatics C harges and their conservation; Coulomb’s law -forces between two point electric charges - Forces between multiple electric charges-superposition principle. Electric field – electric field due to a point charge, electric field lines; electric dipole, electric field intensity due to a dipole - behaviour of a dipole in a uniform electric field. Electric potential - potential difference-electric potential due to a point charge and dipole- equipotential surfaces – electrical potential energy of a system of two point charges. Electric flux- Gauss’s theorem and its applications . Electrostatic induction-capacitor and capacitance – dielectric and electric polarisation – parallel plate capacitor with and without dielectric medium – applications of capacitor –
