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

Formule

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

Stapsgewijze handleiding

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

Uitgewerkte voorbeelden

Invoer
v = 0.9c (90% light speed)
Resultaat
γ ≈ 2.29, time dilation factor = 2.29
Significant relativistic effects

Veelgemaakte fouten om te vermijden

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

Veelgestelde vragen

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).
