mouvement systeme:
  trajectoire
  -ensemble de position successive
  rectiligne, circulaire curviligne...
  vitesse moyenne deux point 
  -v1=M1M2/delta T
  vitesse instantane un point
  -v1=M1M2/delta T  delta court
principe inertie 
  si les forces qui exerce sur un
  systeme se compensent, alors le 
  systeme poursuit son mouvement
  de repos ou de mouvement rectilige
  uniforme le vecteur vitesse
  ne varie pas 
  
vecteur vitesse :
  -Vi=MiMi+1/ti+1-ti
vecteur variation de vitesse 
 -delta v= v2-v1

moyenne(m)F=m*delta v/delta t
moyenne(m)F en newtons
m en kg
delta v en m.s-1
delta t en sec
