CDS Physics Notes

SI units of pressure and the spring constant, the atmosphere and the bar, length prefixes from kilo to nano, the nanoscale, and dimensional formulas.

Distance and displacement, average speed, the equations of motion, motion graphs, adding and resolving vectors, free fall and horizontal launch, and uniform circular motion.

Inertia and the three kinds of equilibrium, the second law as a change of momentum, impulse, and the conservation of momentum with recoil.

Work and when it is zero, kinetic and potential energy, energy in a swinging pendulum, and power with the least power to lift a load.

Newton's law of gravitation and how the force scales, weight, mass and g, the nearest stars and constellations, the Lagrange points and the GMRT.

Pressure and pressure at a depth, Pascal's law, the buoyant force and floating, the density of a mixture, and Hooke's law with the spring constant.

Temperature scales, conduction, convection and radiation, calorimetry, latent heat and evaporation, the triple point, and the ideal gas.

Longitudinal and transverse waves, the wave equation, the speed of sound in different media, pitch and loudness, echoes, and ultrasound.
