of the bodies in the next time step. In a shaker ball mill, balls move in a gravitational force field. The general equation of motion of a body in a force field is given according to the 2nd Newton's law. For the gravitational field, this equation can be solved analytically. The solution is x(t +∆t)=x(t)+v(t)∆t+g ∆t2 2,v(t+∆t)=v(t)+g∆t, (1)
