## Relativistic Momentum
Classical momentum (p = mv) is only an approximation at low speeds. The correct formula includes the Lorentz factor.
### Formula
**p = gamma * m0 * v**
As v approaches c, momentum grows without bound even though the velocity barely changes. This is why it takes infinite energy to accelerate a massive particle to c.

计算示例
Electron at 0.9c.
- gamma = 2.294
- p_rel = 2.294 * 9.109e-31 * 2.698e8
- p_rel = 5.639e-22 kg m/s
- p_classical = 9.109e-31 * 2.698e8 = 2.458e-22 kg m/s
- Relativistic is 2.29x larger
