good afternoon, I am currently reviewing for the last time, i have question about the difference between -kx (k is spring constant and x is amount of compressed) and 0.5kx^2. I know 0.5kx^2 is elastic potential energy, what is -kx exactly and the difference between them

F = - kx, aka Hooke's law 는 spring 이 늘어나거나 줄어들었을 때 본래 길이로 돌아가려고 하는 restoring force 입니다. 

에너지와 force 는 다른 것입니다.
