im trying to inform. if i hit a nail side on it bends it?(plain was no hammer) If i hit it straight (roof clapsing) must of also fell straight down and not uneven. the hammer slows down as the energy is transfered to the nail so reducing speed as it hits resistance.plus numerouse hits maybe needed, again shown as a stop and start and shown as delayed time.. I know this couse i do it on a daily basis. if you mean it collapsed from the top down then wrong. It fell at free fall speed.(took secounds to collaps becouse no resistance) meaning there is no resistant. Its pyhsically impossible, (i mean we can't break the laws of physics hope that helps) thank you for your reply.
