 ```If a force of 50 N stretches a spring 0.10 m, what is the spring constant? I know that if you double the weight you double the force but i do not know what the equation for the spring constant is.```
 ```Search google for Hookes law. ://www.google.com/search?num=20&complete=1&hl=en&lr=&newwindow=1&safe=off&q=hookes+law&btnG=Search```
 ```To first order in x, that is, linear in x... springs are described by Hooke's law: F = -k*DeltaX This equation has a lot of assumptions importantly a spring confined to 1D-motion. But basically it just says that the force required to compress or stretch the spring in one direction by DeltaX is directly and linearly proportional to the displacement DeltaX. So the constant "k" is a measure of how strong the spring is, a bigger k means a lot more force is going to be required to stretch/compress the spring.. think shocks on a car.. and a smaller k means less force... think rubberband, I guess. Hope that helps...```
