Relativistic mechanics is the branch of mechanics that studies the motion of particles and systems at speeds comparable to the speed of light. It incorporates Einstein's special theory of relativity, which modifies Newton's laws of motion to account for relativistic effects such as time dilation and length contraction.
In relativistic mechanics, the relationship between energy, momentum, and mass becomes crucial, with the famous equation E=mc² showing the equivalence of mass and energy. At low speeds (compared to the speed of light), relativistic mechanics reduces to classical Newtonian mechanics as a limiting case.

Visualize how energy and momentum relate in relativistic mechanics compared to classical mechanics.
In particle accelerators like the Large Hadron Collider, protons are accelerated to speeds extremely close to the speed of light, requiring relativistic mechanics to accurately predict their behavior and collision outcomes.
For spacecraft traveling at significant fractions of light speed, relativistic effects become important for navigation, communication, and life support systems. Time dilation could allow astronauts to travel vast distances within their lifetimes.
