WitrynaThe most remarkable and unexpected fact about falling objects is that, if air resistance and friction are negligible, then in a given location all objects fall toward the center of Earth with the same constant acceleration, independent of their mass. WitrynaAs soon as the object makes contact, the force of the ground acting upward on the object causes a deceleration, which presumably occurs until the object reaches a velocity of 0. This situation is clearly dependent not only on the force applied but also the time that it was applied.
