In all applications of force, all components, internal or external, moving or otherwise, have inertia associated with their mass and geometry. The inertia of the components, internal or external, moving or otherwise, is detrimental to the precision and / or accuracy of the force being applied by and / or to the system, whether the force is applied internally or externally to the system. A motorbased system and / or a method involves mitigating and / or reducing force errors caused by the inertia of the components, internal or external to the system, moving or otherwise, in systems built for the application of force, the forces being internal or external to the system. This is achieved, in part, by addressing the inertial effects of components in the load-application path, including a motor and / or other force-generating devices, force transmitting elements, and carriers of force between a motor and those elements that contribute to force error due to inertial effects.

Acoustic traps use forces exerted by sound waves to confine and transport small objects. The dynamics of an object moving in the force landscape of an acoustic trap can be significantly influenced by the inertia of the surrounding fluid medium. These inertial effects can be observed by setting a trapped object in oscillation and tracking it as it relaxes back to mechanical equilibrium in its trap. Large deviations from Stokesian dynamics during this process can be explained quantitatively by accounting for boundary-layer effects in the fluid. The measured oscillations of a perturbed particle then can be used not only to calibrate the trap but also to characterize the particle.
