Any two objects, irrespective of their masses or any other properties, when dropped from the same height and falling freely will reach the earth at the same time. How? Give an example.

Value of g is constant for all the objects at any given pace on the earth. Hence, if any two objects (irrespective of their masses or other properties) are dropped from the same height, then these objects will fall freely and touch the ground at the same time. To support this, Galileo performed an experiment around 1590 in the Italian city of Pisa. He dropped two spheres of different masses from the leaning tower of Pisa and demonstrated that both the spheres reached the ground at the same time.
