What does the k mean in Hooke’s law?

K represents the constant of proportionality, also known as the ‘spring constant.’ In layman’s terms, the k variable in Hooke’s law (F = -kx) indicates stiffness and strength. The higher the value of k, the more force is needed to stretch an object to a given length. This value is dependent on the object’s material alongside its shape and proportions.
