Newtonian and Maxwellian mechanics don't work so well on small particles, like electrons. Quantum Mechanics doesn't work so well in the macro world we perceive with our senses. Heisenberg's uncertainty principle works well with small particles like electrons, but has no meaning when we are talking about a futbol. When you speak of the laws of physics, it usually depends on the size of the universe you are considering. We don't really have a unified theory that explains all things. The holy grail being the unified force theory. So, to answer your question, Newtonian laws apply to a futbol (or baseball), but Quantum physics applies to the atoms that make up the matter in the ball. And nuclear physics will hurt your head. Nuclear physics and Microsoft(R) Vista(R) should be avoided in order to have a nice day.
