It breaks down in two regimes: Very high speeds (approaching c): Special relativity replaces ma with d(gmv)/dt, where g = 1/ SQRT (1 - v?/c?). For v << c, g ~= 1 and we recover F = ma. The LHC protons are travelling at 0.9999997c -- for those, relativistic corrections are enormous and F = ma would give completely wrong predictions. Atomic and subatomic scales: quantum mechanics governs the behaviour of particles at the scale of atoms. Position and momentum can't both be known precisely (Heisenberg uncertainty principle). The classical trajectory described by F = ma simply doesn't exist at quantum scales -- you have probability amplitudes and wavefunctions instead. -- Physics Funamentals, 2026
