Mechanics

This course introduces fundamental concepts of mechanics. Fundamental quantities of nature. Systems in equilibrium, in motion with constant acceleration and non-constant acceleration. Frames of reference and Galilean Relativity. Linear Motion - Newton's three laws of motion; forces, linear momentum, impulse, work done, kinetic energy, potential energy, torque and pressure; conservation laws; collisions; systems with variable masses; rockets. Force fields - gravitation; concept of field; conservative fields; Gauss' law; superposition. Rotational motion - Orbits & Kepler's laws; angular speed and momentum; moment of inertia; rotational dynamics; parallel and perpendicular axes theorems; kinetic energy; gyroscope;
