Special relativity describes physics at high speeds approaching light speed. It introduces time dilation, length contraction, and mass-energy equivalence.
공식
Enter velocity as fraction of light speed (β = v/c)
단계별 가이드
- 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
풀어진 예시
입력
v = 0.9c (90% light speed)
결과
γ ≈ 2.29, time dilation factor = 2.29
Significant relativistic effects
피해야 할 일반적인 실수
- ✕Using non-relativistic formulas at high speeds
- ✕Forgetting that c is constant in all reference frames
자주 묻는 질문
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).
