Tension springs and compression springs work in opposite ways and use many different end devices or hooks to secure the tension source for tension springs.
Compression springs act in the direction when pressed, extension springs act in the direction when stretched or drawn, and when stretched, the ends of the springs are pulled back together, and this is how the forces acting on each spring relate to each other.
On the other hand, the forces act on each other and the reaction forces act on each other. Like compression springs, extension springs absorb and accumulate forces. But unlike compression springs, in most extension springs there is usually a certain degree of tension even without a load, and this initial tension determines how tight the extension spring is without a load.
