> =C3=87a prouve que Vr =3D a.t et non pas a.Tr mais comme Tr =3D t.sqrt(1-=
v/c=C2=B2)
> Vr =3D a.Tr/sqrt(1-v/c=C2=B2) =3D a.Tr.sqrt(1+Vr=C2=B2/c=C2=B2)

 poser Ar =3D a.sqrt(1+Vr=C2=B2/c=C2=B2).
Je n=E2=80=99ai pas tout suivi cette discussion, mais Ar, Tr, Vr sont les g=
randeurs r=C3=A9elles, soit respectivement a, t, v, en m=C3=A9canique class=
ique et relativiste:=20
v =3D dx/dt, a =3D dv/dt d=E2=80=99o=C3=B9 Vr =3D v =3D a t =3D Ar Tr.
