Thanks. So, is it possible to design a method of collapse whereby the falling mass can add sufficient energy in each impact to cause the overall speed to come close to that of a freefall drop? I mean, concrete has got to be thousands of times more resistant than air so is this a ridiculous idea?

Cheers, this is getting complicated :rolleyes: My question concerns a hypothetical demolition, where I am interested in the efficiency of the event. If a weight is dropped on the uppermost floor that carries sufficient force to collapse that floor, can this process be continued in some...

OK... It makes sense to me that the same mass, broken up once already, would not have the same impact. So, what I need to know is what the force of the two impacts would be, relative to each other. Would the broken-up mass - say, 1kg of concrete broken up into ten gram pieces, average - hit for...

Hi everyone. I'm not a physicist but I need some help. In the hypothetical situation of a 1 kg block of concrete being dropped onto a concrete slab from 3 metres, the force of the impact is easy to calculate. However, if one were to pick up the pieces and re-drop them, what would be the force...
