Simon Stevin, Dutch engineer, inventor, and mathematician published results from a gravity experiment in 1586, whereby proving that objects with different masses fall at the same speed. Stevin dropped two lead balls, one ten times as heavy as the other, a distance of 30 feet and both simultaneously hit the ground. The results refuted Aristotelian assertion that objects of different weights fall at different speeds, preceded in 1583 by Galileo Galilei’s famous gravity studies.

Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work. When this happens, an object may be falling, but it is not in free fall.

Jun 20, 2011 – Consequently, the acceleration is a = F m = G M R 2 , which is independent of the mass of the object. Hence any two objects that are subject only to the force of gravity will fall with the same acceleration and hence they will hit the ground at the same time.
