## relativistic mechanics

[‚rel·ə·tə′vis·tik mi′kan·iks]
(relativity)
Any form of mechanics compatible with either the special or the general theory of relativity.
The nonquantum mechanics of a system of particles or of a fluid interacting with an electromagnetic field, in the case when some of the velocities are comparable with the speed of light.

## Relativistic Mechanics

the branch of theoretical physics that considers the classical laws of motion of bodies or particles at rates of motion ν comparable with the speed of light. Relativistic mechanics is based on the theory of relativity. The basic equations of relativistic mechanics—the relativistic generalization of Newton’s second law and the relativistic law of conservation of energy-momentum—satisfy the requirements of Einstein’s relativity principle. In particular, it follows from these equations that the speed of material objects cannot exceed c, the speed of light in a vacuum. When ν ≪ c, relativistic mechanics reduces to classical Newtonian mechanics.

Guided by the resulting analogies that relativistic mechanics and its underlying hyperbolic geometry share with classical mechanics and its underlying Euclidean geometry, we are able to present analogies that Newtonian systems of particles share with Einsteinian systems of particles in Sections 3 and 4.
