How do 2 objects of different weights fall and touch the ground at the same speed and time?

326 views

Imagine 2 objects, 1 is a 50kg dumbbell and 1 is a 1g feather, how is it possible that they will fall and touch the ground at the same speed and time assuming they are dropped from the same height?

I must be understanding this completely wrong.

Edit: I definitely understood it completely wrong because I did not know it only applied to objects in space. That makes much more sense.

First of all, this is only in a vacuum, where air resistance does not exist. Typically it still doesn’t matter *too much*, but with the example of a feather, it definitely matters.

The reason everything accelerates equally, is because for every “extra pull” they get from gravity (for being more massive), they have an equal “extra resistance to acceleration”, which we call inertia.
