Vecteur Variation Vitesse
⮕     ⮕      
 ΔvMi⮕Mi+1=VMi+1-vMi
          ⮕       ⮕    ⮕
Exemple  Δv4⮕5= v5-v4=v5+(-v4)
Exemple valeur
 
  Δv4⮕5= 3.5cm x Echelle
        =3.5 x 4
        =14 m/s

deuxieme loi de newton
⮕
ΣF=mx Δv/ Δt

Exemple Systeme terre 
Force=Fs/t=GxMtxMs/D2

ΣF=MtxΔv/Δt

soit Fs/t=MtxΔvxΔt

demonstration 

Δv=ΣF x Δt/m
