Pour une même vitesse d'éjection, on constate que la distance parcourue est maximale pour un angle de 45°. Ceci s'applique pour le boulet du canon ou pour le javelot du sportif.
La résistance de l'air étant négligée, la trajectoire est une parabole exacte, d'où le nom de "chute libre parabolique". La chute libre verticale n'est qu'un cas particulier de la chute libre parabolique.
Cliquer puis faire glisser les poignées du canon pour modifier l'angle de tir.
Cliquer sur 'lecture' pour tirer et 'pause' pour stopper le mouvement.
Cliquer sur 'théorie' pour afficher l'environnement mathématique. The angle of the barrel can be changed as well as its initial speed.
For the same speed of ejection, it is found that the distance is a maximum angle of 45 °. This applies to the cannon ball or javelin sports.
The air resistance is neglected, the trajectory is an exact parabola, hence the name "parabolic free fall." Free vertical drop is only a special case of parabolic free fall.
Click and drag the handles of the gun to change the angle of the shot.
Click on 'play' to shoot and 'pause' to stop the movement.
