Normal and anomalous diffusion in a bouncing ball over an irregular surface

The problem of a bouncing ball on a non-planar surface is investigated. We discovered that surface undulation adds a horizontal component to the impact force, which acquires a random character. Some aspects of Brownian motion are found in the horizontal distribution of the particle. On the x-axis, normal and super diffusion are observed. For the probability density’s functional form, a scaling hypothesis is presented.
