Physical quantities with m, , c<br />

For a particle <strong>of</strong> mass m, we can use physical constants and c, to<br />

form dimensionally correct quantities<br />

m = [mass]<br />

mc = [momentum]<br />

mc 2 = [energy]<br />

mc 2 / = [time] −1<br />

/mc 2 = [time]<br />

/mc = [length]<br />
