Physics
Study GAT Physics at the official UPSC depth, from matter and motion to optics, electricity, magnetism and everyday devices.
In short
GAT Physics is Section A of Part B. The official scope is elementary breadth: properties of matter, mechanics, heat and sound, light, magnetism and electricity, and the working principles of everyday devices. JEE-level derivations are out of scope.
Physical properties and states of matter; mass, weight, volume, density, specific gravity; Archimedes' principle; pressure and barometer; motion, velocity, acceleration, Newton's laws, force, momentum, equilibrium, gravitation, work, power and energy.
Temperature, heat, change of state, latent heat, transfer of heat, sound waves and simple musical instruments.
Rectilinear propagation, reflection, refraction, spherical mirrors, lenses and the human eye.
Natural and artificial magnets; Earth as a magnet; static and current electricity; conductors and non-conductors; Ohm's law; simple circuits; heating, lighting and magnetic effects; electrical power; primary and secondary cells; use of X-rays.
Simple pendulum, pulleys, siphon, levers, balloon, pumps, hydrometer, pressure cooker, thermos flask, gramophone, telegraph, telephone, periscope, telescope, microscope, mariner's compass, lightning conductors and safety fuses.
Teach concept, unit, basic relationship and everyday application. JEE-level derivations and advanced numerical problem sets are not imported.
Scope authority is the official UPSC NDA notification. Section proportions, where shown, are official approximate syllabus proportions and never predicted weightage.
