Relative Velocity & Relativity
scienceCalculate relativistic velocity addition, Lorentz factor, time dilation, and length contraction.
Enter speeds as fractions of light speed c (0 ~ 0.999). E.g. 0.8 means 0.8c.
u = 0.97561 c
아무리 빠른 두 속도를 더해도 빛의 속도 c를 초과할 수 없습니다.
u = 1.60000 c
빛의 속도에 가까워질수록 고전역학은 심각한 오차를 나타냅니다.
Einstein's Special Relativity
Formulated in 1905, special relativity shows that measurements of time and space are not absolute, but depend on the relative velocity of the observer, bound universally by the invariant speed of light c.
