Hence, by using this model we can, at least, get some idea of how air resistance modifies projectile trajectories.The air resistance force increases which causes the magnitude of the acceleration to decrease. During this time the object is still increasing its speed. At a given point the air resistance, or drag, is equal to that of the weight.
