Everyone has heard the story of Issac Newton being struck on the head by a falling apple. This famous story perfectly illustrates Newtonian physics. Simply put, Newtonian physics is the study of the laws of physics that were studied by Newton and later physicists that deal with the “everyday world” physical events that can be more easily perceived and seen. These events are governed by the collection of atoms that form physical structures.
Quantum physics is the study of particles much smaller than those dealt with in the Newtonian world.
