Module 01 foundation
From measurement to relativity
Connect measurements to motion, conservation, waves, fields, and relativistic spacetime.
- 01
Measurement, dimensions, and useful uncertainty
Turn observations into quantities, check equations before calculating, and report what a measurement actually supports.
22 min - 02
Kinematics: reading a trajectory
Connect position, velocity, and acceleration while keeping coordinate choices distinct from physical motion.
25 min - 03
Newton's laws and choosing the system
Use free-body diagrams to connect interactions to acceleration without confusing forces on different objects.
25 min - 04
Work, energy, and changing the question
Predict changes in speed from energy transfers while stating where friction, potentials, and system boundaries enter.
26 min - 05
Momentum, impulses, and collisions
Track momentum across a system boundary and distinguish momentum conservation from kinetic-energy conservation.
26 min - 06
Rotation, torque, and angular momentum
Explain why force placement matters and connect rotational motion to angular momentum about a stated origin.
28 min - 07
Harmonic motion and the oscillator model
Derive oscillation from a restoring force, connect phase to initial data, and distinguish free motion from damping and driving.
28 min - 08
Waves, phase, and interference
Follow a disturbance through space and understand interference as addition of amplitudes under a linear model.
29 min - 09
Electric and magnetic fields as local physics
Replace action-at-a-distance sketches with fields, the Lorentz force, and a first account of field energy and waves.
31 min - 10
Special relativity: events before intuitions
Use Lorentz transformations, invariant intervals, and proper time to compare measurements without inventing a preferred frame.
