## Relativistic Mass
As an object approaches the speed of light, its inertia increases, making further acceleration progressively harder.
### Formula
**m_rel = m0 * gamma = m0 / sqrt(1 - v^2/c^2)**
Note: Modern physics prefers the concept of invariant (rest) mass. The "relativistic mass" is the total energy divided by c^2, but it is a useful pedagogical tool.

Ejemplo Resuelto
1 kg object at 0.9c.
- gamma = 1 / sqrt(1 - 0.81) = 2.294
- m_rel = 1 * 2.294 = 2.294 kg
- Mass appears 129.4% larger.
