## Lorentz Length Contraction
Objects moving at relativistic speeds appear shorter in the direction of motion.
### Formula
**L = L0 * sqrt(1 - v^2/c^2) = L0 / gamma**
- *L0* = proper length (measured at rest)
- *v* = relative velocity
Contraction occurs only along the direction of motion. Transverse dimensions are unaffected.

计算示例
A 100 m spaceship at 0.9c.
- beta = 0.9, gamma = 2.294
- L = L0 / gamma = 100 / 2.294
- L = 43.59 m
- The ship appears 56.4% shorter.
