    Discuss the definitions with the pupils and write a commun definition of trajectory and speed. Exercices to calculate speed at home.
Notes:
The videos are projected to the class so as to have a discussion and a commun definition that we write together on the computer project to the class. Trajectory / trajectoire : the way the object moves / chemin suivi par un objet au court du temps. Average Speed / Vitesse moyenne : distance divided by time / distance parcourue divisée par la durée du parcours
