Summary edit
| Description |
English: A solid is modeled by two rigid bodies linked by a spring. on the top picture, the velocity of the body is uniform.
A collision creates a temporal discontinuity of the overall speed. If it occurs on the left part (bottom picture), then the right part keeps its initial velocity (inertia, Newton's first law) until the shock wave propagates through the spring. The temporal discontinuity of the speed thus reslts in a spatial discontinuity of the velocity field.
Français : Un solide est modélisé par deux corps indéformables reliés par un ressort. Sur l'image du haut, la vitesse est uniforme.
Une collision crée une une discontinuité temporelle de la vitesse globale. Si elle se produit sur la partie gauche (image du bas), alors la partie droite conserve la vitesse initiale (principe d'inertie, première loi de Newton) jusqu'à ce que l'onde de choc l'ait atteinte. |
