the rotational analog of spring constant is known as rotational stiffness. The formula for Hookes law specifically relates the change in extension of the spring, x, to the restoring force, F, generated in it: The extra term, k, is the spring constant. The object of this virtual lab is to determine the spring constant k. Displacement is measured in centimeters. How to Calculate a Spring Constant Using Hooke's Law. The variables of the equation are F, which represents force, k, which is called the spring constant and measures how stiff and strong the spring is, and x, the distance the spring is stretched or compressed away from its equilibrium or rest position.\r\n\r\nThe force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium.\r\n\r\nIn Hookes law, the negative sign on the springs force means that the force exerted by the spring opposes the springs displacement.\r\n

Understanding springs and their direction of force

\r\n\r\n\r\nThe preceding figure shows a ball attached to a spring. Check out, All tip submissions are carefully reviewed before being published. The gravitational force, or weight of the mass m acts downward and has magnitude mg, If you doubled the length of the spring, on the other hand, its spring constant would be half what it was. The M ass on a Spring Interactive provides the learner with a simple environment for exploring the effect of mass, spring constant and duration of motion upon the period and amplitude of a vertically-vibrating mass. F = -kx. The spring constant is determined using the value of the force applied and the displacement caused by Force on the spring.
