You can think this if you are the idiot from the video who things the building is in some "weightless state" in space where there is no gravity. Then there would be only "the force of the fall" which would be obviously slowed down...
But we are not in the weightless state, are we? You definitely are in very overweight state yourself so you should know better. So if one level fails because it cannot hold the weight, then adds the "free fall momentum" to the force, even if you remove all the free fall momentum, the next level of the building have to carry the initial weight + weight of the just-failed level. Obviously it won't be able to, so it will fail too.
So if every level has weight "1", that means 20 level "top" of the building has weight 20.
Every failed level adds 1 to the 20. For 5 failed levels under the failed top, that means 20+1+1+1+1+1=25 <= as you can see, it gets worse over time and the building hence collapses faster.
