  Simulation of a system consisted of free particle bouncing on a vertically
vibrated based is performed. Two different states, which are steady and
unsteady energy transfer state are found. The vibrating based is hold at
constant vibration frequency $f = 0.1$ as the vibration amplitude $A$ varied.
Sinusoidal form is used. Granular temperature $T_g$ as function of based
velocity and coefficient of restitution is used but shown no role in
determining energy transfer state of the system. Peak of free particle
trajectory $x_m$ around value 20 seperate region of the two states.
