Structural Biochemistry/Enzyme Catalytic Mechanism/pingpong mechanism. Ping Pong is also called the double placement reaction and it means that one or more products are released before all substrates bind the enzyme. One key character of this reaction is the existence of a substituted enzyme intermediate, in which the enzyme is temporarily modified.
Assuming that the experiments are properly controlled, that is, everything but the ball type is the same, then what is different is how much energy is lost in the ball. Ping-pong balls are very stiff and springy -- they lose only a small fraction of their energy when they bounce on a hard surface. On a soft, squishy surface, the ping-pong ball may bounce less well (but then again, the other balls may bounce less well also). Some surfaces are very complicated, like a mattress.
