Answer 2

Effects an action can have on an object:

• Modifying its form
• Modifying its tragectoire
• Modifying its speed
• Make it move “le mettre en mouvement”

Answer 4

A diagramme Object-Interaction has:

• The “objet au quelle on s’interesse, aussi appeller le systeme
• Un action à distance (exemple: La Terre) dans un cercle, relier a l’objet avec une double fleche pointé
• Un action de contacte dans un autre cercle, relier a l’objet avec une double fleche

Le nombre d’actions mechaniques (à distance ou de contacte) depend des actions surposer sur l’objet
