Velocity = length time, acceleration=length(time)2 Length=(Velocity)2acceleration         i.e,  L'=v'2a',L=v2a L'L=(v'v)2  (aa')=(α2β)1αβ=α3/β3 Now,  m'=F'a',m=Fa m'm=F'Faa'=1αβ×1αβ=1α2β2

Time = velocity/acceleration, i.e.,

T'=v'a'  and  T=va T'T=v'vaa'=α2β1αβ=αβ2

Momentum = mass × velocity

p'=m'v',P=mv,p'p=m'mv,v=1α2β2α2βα2β=1β4
