Isaac newton developed a theory of gravity by first considering galileo’s experiment of dropping objects of different masses from the leaning tower of pisa. galileo found that, when air resistance is negligible, all objects took the same amount of time to hit the ground when dropped from the top of the tower. watch the astrotour on velocity, acceleration, and inertia, and then choose the answer that best describes what galileo’s experiment implies.
