Theoreme de l energie cinetique
  Ec=0.5*m*v**2
  Ec en J
  m en kg
  v en m/s

Travail d une force constante
  Wab(F)=F*AB*cos(alpha)
  Wab(F) en J
  F en N
  AB en m

Travail du poids
  Wab(P)=m*g*(Ya-Yb)
  Si Ya<Yb alors Wab(P)<0 donc le travail du poids est resistant
  Si Ya>Yb alors Wab(P)>0 donc le travail du poids est moteur
  Si Ya=Yb alors Wab(P)=0 donc le travail du poids est nul

Travail d une force de frottements
  Wab(f)=-f*AB
