The larger the force pulling on a spring, the greater the length in the spring and the more energy that is stored in that spring. When looking at a spring there is a gradient that determines how much force much be used to sqeeze or stretch a spring a given amount. When a spring is stretched, the greater the force that is applied, the greater the change in length of the spring and the greater the amount of energy that is stored in the spring. A link is supplied to the Wikipedia article on the spring (device).
It is easy to observe that when spring is cut into two halves it is difficult to strech the spring with half length than full length.so in general we can say spring constant is inversly preportional to length
jedi or the dark side?
Longer length requires more power.
it streches or compresses
It stretches.
Stretching force
Yes a physical property "Elasticity" is the cause for such a stretching
Depends on how strong the metal is, how much of it there is, and how big the force is. Strong metal, lots of it, only little force - nothing happens. Strong metal, small part, little force - the metal will stretch and then spring back when the force is removed. Strong metal, small part, more force - the metal will stretch permanently. Strong metal, small part, even more force, the metal will stretch until it snaps. etcetc
the relation between force (F) and elongation (x) is F = kx where k is the spring constant. The stiffer the spring, the higher the force needed to get a certain elongation; or, for a given force, the elongation will be less for a stiffer spring
it is isn't really a force but when something expands, it's called tension.

One common way to measure them (there are others) is with a spring. The extension of the spring is proportional to the force applied.
The relationship is Hooke's Law: the extension of a spring is directly proportional to the force applied.
