Je vais vou= s aider. Un point M=E2=80=99 mobile par rapport =C3=A0 un espace E a pour c= oordonn=C3=A9es (x=E2=80=99, y=E2=80=99, z=E2=80=99) dans cet espace.=20 On a OM=E2=80=99 =3D OM + MM=E2=80=99. Prenons un d=C3=A9placement suivant = l=E2=80=99axe des x, on obtient: x=E2=80=99 =3D x + vt si M=E2=80=99 va dans le sens des x positifs et x=E2= =80=99 =3D x - vt dans le cas contraire. C=E2=80=99est du niveau seconde je pense.
