classical physics (uncountable)
(physics) all aspects of physics developed before the rise of quantum mechanics
Certainly we do not need quantum mechanics for macroscopic objects, which are well described by classical physics – this is the reason why quantum mechanics seems so foreign to our everyday existence. Alain Aspect
According to theories of classical physics, energy is solely. Source: Internet
In 1910, Einstein pointed out the anomalous behavior of specific heat at low temperatures as another example of a phenomenon which defies explanation by classical physics. Source: Internet
Bohr's correspondence principle demands that classical physics and quantum physics give the same answer when the systems become large. Source: Internet
Despite the name, particles do not literally spin around an axis, and quantum mechanical spin has no correspondence in classical physics. Source: Internet
For example, the de Broglie wavelength of a tennis ball is insignificantly small, so classical physics is a good approximation to use in this case. Source: Internet
