Relativity
Gravitational Redshift Calculator
Compute the observed frequency of light or electromagnetic radiation emitted near a massive object, accounting for gravitational redshift predicted by General Relativity. Essential for astrophysics, pulsar timing, and GPS system design.

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.
