Question

What is the spring constant? Describe the definition and explain its meaning in your own words.

Answer 1

Spring constant is measurement which is constant for a particular spring that gives the measure of "stiffness" of a spring.

Spring constant is given by the ratio of force to displacement caused by this force or we can say, spring constant is a measure of force required to compress/stretch a spring through a unit length.

Spring constant = (Force) / (displacement caused by this force)

Unit of spring constant = N/m (newton per meter)

Dimensional formula = [MT^-2]
