Ball Drop Impact test - equations?? I'm hoping someone can point me in the right direction here. =) I'm testing a bunch of materials by dropping a steel ball from increasing heights until the materials break. So I have a bunch of data that looks like this: Material A - broke at 18cm Material B - broke at 20cm Material C - broke at 12cm etc. How can I turn this data into usful information (i.e. how can I say Material A can take x amount of impact, Material B can take y amount of impact etc..) Its been awhile since I've taken physics.. at first I was thinking force, but F=ma does not take height into consideration.... height or velocity would have to be included... Can someone please point me in the right direction? Thanks!
