The reason why the cup got more kinetic energy is because when you out the cup on the table it received more kinetic energy. The formula for kinetic energy consists of speed and mass. (You multiply speed times mass.) So when you put the cup on the table, it's speed times its mass gave it a higher kinetic energy amount. The table lost kinetic energy because when the cup came down, some energy was transfered to the cup. So in conclusion, the cup got more kinetic energy and the table lost some.
