Newton’s second law
F = ma; reverse modes divide force by a nonzero acceleration or positive mass. Inputs normalize through kilograms, meters per second squared, and newtons.
Safety boundary
Signed force and acceleration are preserved, while mass cannot be negative. This arithmetic does not determine structural capacity, safe loads, collision forces, lifting safety, or bolt preload.
