Daedalus Posted September 22, 2010 Report Share Posted September 22, 2010 How about dropping a piece of inert metal with a known mass from a known height on it and measuring the indent? 1 Reply Link to post Share on other sites More sharing options...
Sandwich Posted September 22, 2010 Report Share Posted September 22, 2010 With a ruler? Use a thin bit of wood, put it in the indent to see how deep it is and then measure the depth off the wood. The only problem is that it wouldn't be a standardised sort of measurement and would only mean something if you said it was relative to something else.Why don't you ask your teacher for ideas? They might have some proper equipment. 1 Reply Link to post Share on other sites More sharing options...
