In a vacuum, there is no air resistance. The only force acting on a falling object is gravity. According to Galileo's principle of falling bodies, objects in free fall under gravity accelerate at the same rate regardless of their mass or composition, provided air resistance is negligible or absent (as in a vacuum). The acceleration due to gravity (g) is constant for all objects at a given location.
