Explanation
A Planck momentum is equal to the Planck mass mp multiplied by the speed of light c and is defined by
where
mp Planckmass c Speed of light ℏ Reduced Planck constant lp Planck length
Alternative 1
It can also be expressed as
where
mp Planckmass c Speed of light ℏ Reduced Planck constant G Gravitational constant
HistoryThe name pays tribute to the German physicist Max Planck (1858 - 1947). |
