Work Step by Step

Classical physics includes the study of Newton’s laws of motion (known as classical mechanics), and the study of Maxwell's equations for electricity and magnetism. Classical physics applies to relatively large, slow objects. In the 20th century, physicists discovered that classical rules didn’t apply to very small particles. Quantum physics was then developed, where quantities such as energy, angular momentum, electric charge, and light are "grainy", i.e., they occur in lumps, or quanta. In quantum physics, the line between particles and waves becomes blurry, and the underlying principle is probability.
