If three balls of different materials were dropped at the same time from the same height, which would hit the ground first? (Assume there is no air resistance.)

As Galileo Galilei proved with an experiment in which he put in free fall different objects of different mass, but the same shape, all objects fall with the same acceleration when are allowed to free falling. So, if the initial conditions were the same (height, initial velocity, and time), the three balls would hit the ground at the same time, no matter which material they are made of.

The three ( 3 ) balls will hit the ground at the same time

Given that the initial conditions of the balls which are ; Initial velocity, distance from the ground and Time of drop are the same, the balls will hit the ground at the same time regardless of the materials they are made from.

The acceleration due to gravity is a constant and will have the same effect on the travel time of objects regardless of shape or material provided the initial conditions are the same.

Hence we can conclude that the three ( 3 ) balls will hit the ground at the same time.
