In hooke's law, f spring = k (triangle) x , what does the k stand for?

a. the amount of force acting on the spring

b. the elastic constant, a number that tells the relative strength of the spring

c. the distance the spring stretches

d. the constant of gravity

Hook's law is: F = - K Δx

Where:

F stands for the force that the spring exerts

K is stands for the constant of the spring

Δx stands for the distance the spring is displaced from the equilibrium point.

And the negative sign is due to F is opposite to the direction in which the spring is away from the equilibrium point.

the answer is B. the elastic constant, a number that tells the relative strength of the spring.
