Subject: [Phys-l] Crater Help
I'm trying to run a lab with some conceptual physics students
about crater formation (crater characteristics and their relationshipto
KE/gPE of the "meteorite"), but am having trouble getting anythingother
than deeper/less deep craters with heavier/lighter balls. From thetalk
on webpages discussing the various incarnations of this experiment, Iam
also expecting to get some wider/narrower craters. All of my cratersare
almost exactly the width of the balls. I'm using uncompacted flour.Any
hints?
Thanks,
