Summary and Info
All elementary particles feel gravitation the same. More specifically, particles with different masses experience a different gravitational force, but in such a way that all of them acquire the same acceleration and. given the same initial conditions, follow the same path. Such universality of response is the most fundamental characteristic of the gravitational interaction. It is a unique property, peculiar to gravitation: no other basic interaction of Nature has it.
