I WONDER - What Is Terminal Velocity?

The video explains terminal velocity, a concept where a falling object reaches a constant speed when the force of gravity is balanced by air resistance. It illustrates this with an example of two objects of different weights falling at the same speed due to having the same terminal velocity. This principle was first demonstrated by Galileo Galilei, who dropped two spheres of different weights from the Leaning Tower of Pisa, showing they hit the ground simultaneously.

Why do two objects of different weights hit the ground at the same time when dropped from the same height?

What conclusion can be drawn from Galileo's findings regarding terminal velocity?
