Detailed explanation-1: -In physics, relativistic mechanics refers to mechanics compatible with special relativity (SR) and general relativity (GR). It provides a non-quantum mechanical description of a system of particles, or of a fluid, in cases where the velocities of moving objects are comparable to the speed of light c.

Detailed explanation-2: -The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein; special relativity and general relativity, proposed and published in 1905 and 1915, respectively.

Detailed explanation-3: -Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics.
