Planck momentum

Unlike most of the other Planck units, Planck momentum occurs on a human scale.

The upshot is that Lorentz-boosting a momentum will never increase it above the Planck momentum.

In SI units Planck momentum is approximately 6.5 kg m/s.

Planck momentum is the unit of momentum in the system of natural units known as Planck units.

By comparison, running with a five-pound object (10xPlanck mass) at an average running speed (10xspeed of light in a vacuum) would give the object Planck momentum.
