From measurement to relativity

Connect measurements to motion, conservation, waves, fields, and relativistic spacetime.

  1. 01

    Measurement, dimensions, and useful uncertainty

    Turn observations into quantities, check equations before calculating, and report what a measurement actually supports.

    22 min
  2. 02

    Kinematics: reading a trajectory

    Connect position, velocity, and acceleration while keeping coordinate choices distinct from physical motion.

    25 min
  3. 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
  4. 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
  5. 05

    Momentum, impulses, and collisions

    Track momentum across a system boundary and distinguish momentum conservation from kinetic-energy conservation.

    26 min
  6. 06

    Rotation, torque, and angular momentum

    Explain why force placement matters and connect rotational motion to angular momentum about a stated origin.

    28 min
  7. 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
  8. 08

    Waves, phase, and interference

    Follow a disturbance through space and understand interference as addition of amplitudes under a linear model.

    29 min
  9. 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. 10

    Special relativity: events before intuitions

    Use Lorentz transformations, invariant intervals, and proper time to compare measurements without inventing a preferred frame.
