Spring Constant (k)

Definition

The spring constant, represented by the symbol k, is a measure of how stiff or flexible a spring is. It determines the amount of force required to stretch or compress a spring by a certain distance.

Analogy

Think of the spring constant as the "springiness" factor of a mattress. A high spring constant means that the mattress is very firm and requires more force to compress, while a low spring constant means that the mattress is soft and easily compressible.
