[Phys-L] Re: stretch it a bit

We do the experiment... I hang two identical springs end-to-end and do
the Hooke's law lab (vary weight, record change in length) and repeat
with just one of the springs - use the same weights. I like
graphing...so we graph and calculate the slope (k) for each.

All other factors remaining the same, why are shorter springs stiffer
(higher k) than longer ones? If you cut a spring in half, the spring
constant of either half is twice that of the original spring. What is the
easiest way to analyze this?
