El momento lineal $\bf{p}$ de un cuerpo, referido a un marco $\Sigma$ , se define como

$\bf{p} = m\bf{u}. \label{15.22.1}$

Aquí $m$ y $\bf{u}$ se hace referencia a su masa y velocidad $\Sigma$ . Tenga en cuenta que no $m$ es la masa de descanso.

Ejemplo $\PageIndex{1}$

La masa restante de un protón es de 1.67% 10 ^{- 27} kg. ¿Cuál es su impulso referido a un marco en el que se mueve al 99% de la velocidad de la luz?

Respuesta = 3.51% 10 ^{- 18} kg m s ^{- 1}.
