Yes it does. When an elastic ball bounces from a surface, some of its energy is lost in the ball as well as the surface. The ratio of the final velocity divided by the the initial velocity is equal to the product of the coefficient of restitution of the respective materials. The cof can range to near one for a steel plate and close to zero for a plate of gello. The cof of wood is about 0.60 and that of rubber is about 0.83. So the ball will bounce higher on a rubber surface..
