Q & A: Heavy and Light - Both Fall the Same | Department ...

In the absence of air friction both heavy and light objects will reach the ground at the same time. Galileo deduced this by devising clever experiments with balls rolling down inclined planes. Newton gave it his blessing by observing that a = F/M, i.e. the acceleration of an object is proportional to the force, F, on it divided by its mass, M.
