Detailed explanation-1: -Physics as it developed from the Renaissance to the end of the 19th century is called classical physics . It was transformed into modern physics by revolutionary discoveries made starting at the beginning of the 20th century.
Detailed explanation-2: -The traditional branches of classical physics are Optics, Acoustics, Electromagnetics, and Classical mechanics. With the rapid development of physics, the scope of the subject is growing so large that it is not possible to cover physics under the above branches.
Detailed explanation-3: -1826: Samuel Morey patents the internal combustion engine. 1829: First electric motor built. 1837: Telegraphy patented. 1849: The safety pin and the gas mask are invented.
Detailed explanation-4: -General relativity is the geometrical theory of gravitation published by Albert Einstein in 1915/16. It unifies special relativity, Newton’s law of universal gravitation, and the insight that gravitation can be described by the curvature of space and time.
Detailed explanation-5: -There are two important alternative formulations of classical mechanics: Lagrangian mechanics and Hamiltonian mechanics.
