We derive the equations of motion of a test particle with intrinsichypermomentum in spacetimes with both torsion $S$ and nonmetricity $Q$ (alongwith curvature $R$). Accordingly, $S$ and $Q$ can be measured by tracing outthe trajectory followed by a hypermomentum-charged test particle in such anon-Riemannian background. The test particle is approximated by means of aDirac $\delta$-function. Thus we find a tangible way to observe and measure theeffects of torsion and nonmetricity. Our results are consistent with earlierones derived by Obukhov and Puetzfeld (2014) by means of a different method. Weapply our insight and evaluate how far-reaching the so-called `geometricaltrinity of gravity' really is.
