Relativity
Lorentz Transformation Calculator
Transforms the spacetime coordinates (x, t) of an event from one inertial reference frame to another moving at relativistic velocity. Used in special relativity to reconcile observations made by different observers.

Relativity
Relativistic Momentum Calculator
Compute the relativistic momentum p = γmv of a particle from its rest mass and velocity. Reduces to classical mv at low speeds but grows without bound as velocity approaches c.
