Of course too, 911 was the Classical Physics demo of static --> kinetic energy transference.
Nothing New under the Sun (or the Galaxy.
That collapsing-demo also illustrated the idea of [Power/time] aka Impulse: the accelerated mass above ..as each floor dropped with more K.E. than the last total. tThat horrific metrical clatter. All the way to the ground. Stronger materials and placement made the task re the lower floors--built more ruggedly to sustain the huge static mass above--require even more energy to lose their "walls". There was quite sufficient of that, by then.
F=MA; you can understand a heap about common things around, their motions and limits: from just that simple formula.
AIn't Science wunnaful?
