Vecteur variation vitesse

     delta v.i = v.i+1 - v.i - 1
     
  Ce vecteur s'applique au point 
             M.i
             
             
             
somme des forces sigma F
 = addition des de toutes les
 forces exercée
 
 = m X  Delta V
        ---------

  Plus la masse d'un objet
est grqnde; plus il faudra fournir
de force pour le mettre en mvt

Maintenant les fluides

norme force pressante=

F = P X S


1 Pa = correspond à une f=1N

T°K = t + 273,15

P = f/S 

Statique des fluides
P1V1 = P2V2
P1-P2 Rho X g(Z2 -Z1)
P2 = P1 V1
     -----= ;;;en pa
