WebApr 6, 2009 · work done by spring forces -- positive or negative I have gotten the sign wrong on every single spring force-related problem. I'm pretty sure I'm working out the problems correctly, but the answer turns out to be negative when I have it positive, or positive when I have it negative. WebDec 13, 2016 · F s = k Δ ℓ. where Δ ℓ is the change in the spring length. Suppose you take a spring a metre long and compress it by a millimetre ( 10 − 3 m) then the force is not k times one metre, it is k times the change in the length i.e. k times a millimetre in this case: F s = k × 10 − 3. As you compress the spring more and more the change in ...
