The classical physics is based upon the laws of:

Correct answer: A. Newtonian mechanic

  • A. Newtonian mechanic
  • B. Quantum mechanics
  • C. Wave mechanics
  • D. None of these

Explanation

Classical physics is based upon Newtonian mechanics, also known as classical mechanics. The foundation of classical physics rests on three fundamental laws formulated by Sir Isaac Newton: Newton's First law: This law states that an object at rest will remain at rest, and an object in uniform motion will remain in that motion unless acted upon by a net external force. Newton's Second law: This law relates the net force acting on an object to its mass and acceleration. It is expressed as: F = ma Newton's Third law: This law states that for every action, there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B simultaneously exerts a force of equal magnitude but in the opposite direction on object A.

About Dawn of Modern Physics

Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
