theoreme de lenergie cinetique
ΔEcA->B=Ec(B)-Ec(A)
=W Ab(F)

Ec=1/2 mxv2 
Ec=J
m: masse en kilogramme (kg)
v: vitesse en mètre par seconde (m/s)
Si =0 alors vitesse constante

L’énergie potentielle de pesanteur
EPP=m×g×z
EPP: énergie potentielle de pesanteur en Joule (J)
m: masse en kilogramme (kg)
g: intensité de la pesanteur en m/s2
z: altitude du centre de masse de l’objet en mètre (m).

Energie mécanique
Em =Ec + Ep
