> Not that I'm that good on the physics of breaking rocks but I think I can safely say that there is no theoretical/analytical answer to that question.
With a quick google search it looks like the mining engineers have some models as to how much energy it takes to fracture rock.
Like Olbert said the only real way to be sure is to weigh whole bunch of rocks, drop them from the top of the mount, see what kind of ground they land on, see how far they go, and make some pretty graphs to see if there's a relationship. |
