Inertia at the nanoscale is influenced by quantum mechanical effects and the dominant role of surface forces. Unlike macroscopic objects, where mass is the primary determinant of inertia, at the nanoscale, factors such as van der Waals forces, electrostatic interactions, and even thermal vibrations can significantly affect the inertial properties of nanoparticles. This requires a different approach to analyzing and predicting the behavior of nanoscale systems.
