They pass each other 3 seconds later. B. This assumes that the object is launched from ground level and there is no air resistance. Calculating Position and Velocity of a Falling Object: A Rock Thrown Upward. Gravity The 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 .
