Question

in an experiment involving the spiral spring,f is the residing force and x the extension of the spring. the equation f =-kx gives the relationship between f and x. what does k measure in the experiment?

Answer 1

k is the stiffness of the spring, a constant characteristic of the spring.

k represents a force (N) that should be applied to a spring to extend it by 1 meter;

[k] = N / m
