Wondering Why?

## Why do objects fall at the same speed

Why do objects fall at the same speed

Imagine a feather and a brick, both dropped at the same time and in the same height, which one would reach the ground first? Obviously the answer would be the BRICK. The brick is more massive and heavier as compared to a feather thus making it fall faster. The feather on the other hand will just gently float around instead of directly falling into the ground because it is lighter and tinier.

What really affects the speed of the fall between the feather and the brick is the air that surrounds the objects. According to Galileo Galilei, massive and dense objects have greater air resistanceâ€ as compared to small and loose ones.

But taking the air aside, like in a vacuumed setting, when the feather and brick are dropped at the same time and in the same height, the two different objects would fall with the same speed and hit the ground at the same point in time. Galileo called the concept a free fall motionâ€ wherein all objects would go down at the same speed of acceleration, regardless of the mass. In free fall, the only force that is working upon an object is gravity and nothing else. Galileo also added to his observation that an object, when dropped and falls towards the ground, it picks up a falling rate of 9.8 meters per second, squared.

Also, objects fall at the same speed because of the gravitational field strength. Gravity is what pulls everything towards the center of the Earth, roots of the plants, animals, objects, and even humans. And since gravity is a property of the location that is within the Earth’s gravitational field and not that of the falling object, every known object on Earth’s surface will encounter the same amount of gravitational force and free falls regardless of their mass.
