Physics
Kinematics, circuits, optics, radioactive decay, and spectroscopy.
Physics problems usually reduce to one clean relationship applied without slips: the SUVAT equations for motion, momentum conservation in a collision, Hooke’s law for a spring, Ohm’s law for a circuit, the thin-lens equation for optics, exponential decay for a radioactive sample. Mechanics now runs deeper here, through projectile flight, work and energy, and buoyancy in a fluid, alongside the wave relation that links a wavelength to its frequency. Each instrument keeps its governing relationship one click away and states the assumptions behind it, so you spend your attention on the setup rather than the algebra.
