# Value of spring constant depends upon_______________

The value of the spring constant depends on the elastic properties of the spring.

### Explanation

We know that, in an ideal spring, the spring force is proportional to the displacement (x) of its ends from the equilibrium position. So, according to Hooke’s Law,

Fs = -kx

Where Fs is the spring force, x is the displacement from the equilibrium position and k is the spring constant.

The spring constant is the characteristic property of the spring. It depends upon the material of construction and is measured in the units of N m-1.
