Why do 2 bodies of different masses fall at the same rate?

I don't understand how 2 objects that have different masses or sizes hit the ground at the same time.

The reason it's difficult for us to understand is that we live in a world with air resistance


If we lived in an environment without air resistance, we would experience this phenomenon. But, our reality is we drop a feather and a bowling ball at the same time and the bowling ball rockets to the ground while the feather floats slowly down.

The reason the feather floats slowly and the bowling ball doesn't is because of air resistance.

The most common equation that relates distance and time is:

#d = v_0t+1/2at^2# Note that mass is not part of that equation.
