SC133 · Physics for Engineers I

A knowledge wiki for SC133 — Thammasat University, semester 1. Thirty lectures from measurement to entropy: the complete first course in how the physical world moves, collides, spins, flows, oscillates, and heats.

The course in one paragraph

Mechanics is one long story told twice. First, instant by instant: kinematics describes motion, Newton's laws explain it, and applications pile up — projectiles, friction, circular motion, rotation, gravity and orbits. Then the same story via bookkeeping: energy, momentum and angular momentum are conserved, letting you skip the trajectory and compare before with after. The finale applies both tellings to continuous matter: fluids, oscillations, waves, and thermodynamics — where mechanics meets probability and time gets its arrow.
