What is the spring constant equation?

The equation for the spring force is k = -F/x. This equation is derived from Hooke’s Law, which states that the force needed to extend or compress a spring a certain distance is proportional to that distance. The equation for Hooke’s Law is F=kx, where k is the spring constant.

Hooke’s Law holds true for any type of spring. It also holds true for any elastic body that is deformed and reformed, similar to a spring. Hooke’s Law was determined by Robert Hooke during the 17th century. He first stated that law as a Latin anagram in a newspaper and revealed the answer to the riddle many years later. The law then became a part of physics literature and has described the motion of a spring and elastic bodies ever since.
