Special relativity describes physics at high speeds approaching light speed. It introduces time dilation, length contraction, and mass-energy equivalence.

Formula

Enter velocity as fraction of light speed (β = v/c)

Guida passo passo

1Enter velocity as fraction of light speed (β = v/c)
2The calculator applies Lorentz factor γ = 1/√(1 - β²)
3Results show relativistic effects and mass-energy conversion

Esempi risolti

Ingresso

v = 0.9c (90% light speed)

Risultato

γ ≈ 2.29, time dilation factor = 2.29

Significant relativistic effects

Errori comuni da evitare

✕Using non-relativistic formulas at high speeds
✕Forgetting that c is constant in all reference frames

Domande frequenti

What happens at light speed?

Lorentz factor becomes infinite; mass would become infinite, requiring infinite energy—light speed is unreachable for massive objects.

Is relativity relevant to everyday life?

Yes, GPS satellites account for time dilation (0.38 microseconds/day error without correction).
