Now I got it thank you very much for your support.

Then how would I explain a stretch of x=1m to result in a positive force magnitude ? Let's take K=2N/m F = -2*1=-2N It gives a negative value Whilst with x=-1 F=2N So am I supposed to use |F| to write magnitude or what ?

It goes from the right to the left, and I get that spring force has an opposite direction of the stretching/compression. What worries me is getting a force with a negative value, which is something I have never seen, as I always hear that the magnitude of a force is always positive.

It just goes back to x=0 (and negative values depending on k) under the effect of a force directed from right to left.

Thank you for answering. In fact, yes I have learned about vectors but I personally have never seen a negative magnitude, and since as I have studied the magnitude of a vector is ||F|| = sqrt(Fx^2 + Fy^2 ...) so doesn't this basically mean the magnitude of F is |Fx| ? ( Fx = -kx)

Hello, Following Hooke's law, the force applied by a string on an object attached to one of its ends is F = -kx But here is my question : if we consider the equilibrium coordinate x=0 of a horizontal string, and the string is stretched until its end reaches a coordinate x1>0. By applying hooke's...
