You might see this equation in the case where the problem is in determining what is the force pulling on or .

If you call the equilibrium position of the end of the spring (i.e., its natural position with no forces applied) x = 0, then extending the spring will lead to a positive x, and the force will act in the negative direction (i.e., back towards x = 0). 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 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. W is the weight of the added mass. Since the springs have different spring constants, the displacements are different. How to Calculate a Spring Constant Using Hooke's Law. I actually derived the formula of k = 4^2m/T^2 by differentiating the sin(t) function of displacement twice to find the acceleration, then multiply by mass and divide by amplitude to find spring constant. If you push the spring, however, it pushes back, and if you pull the spring, it pulls back.\r\n
Hookes law is valid as long as the elastic material youre dealing with stays elastic that is, it stays within its elastic limit. If you pull a spring too far, it loses its stretchy ability. The spring constant of the spring is 80 newtons per meter. {"appState":{"pageLoadApiCallsStatus":true},"articleState":{"article":{"headers":{"creationTime":"2016-03-26T17:23:25+00:00","modifiedTime":"2021-10-29T19:44:00+00:00","timestamp":"2022-09-14T18:18:44+00:00"},"data":{"breadcrumbs":[{"name":"Academics & The Arts","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33662"},"slug":"academics-the-arts","categoryId":33662},{"name":"Science","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33756"},"slug":"science","categoryId":33756},{"name":"Physics","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33769"},"slug":"physics","categoryId":33769}],"title":"How to Calculate a Spring Constant Using Hooke's Law","strippedTitle":"how to calculate a spring constant using hooke's law","slug":"how-to-calculate-a-spring-constant-using-hookes-law","canonicalUrl":"","seo":{"metaDescription":"Learn about Hooke's law and how to calculate the spring constant, including the formula and insight on a spring's impact on force. When a spring stays within its elastic limit and obeys Hookes law, the spring is called an ideal spring. This limit depends on its physical properties. Next we appeal to Newton's law of motion: sum of forces = mass times acceleration to establish an IVP for the motion of the system; F = ma. Hookes law gives the force a spring exerts on an object attached to it with the following equation:\r\n\r\nF = kx\r\n\r\nThe minus sign shows that this force is in the opposite direction of the force thats stretching or compressing the spring. In order to continue enjoying our site, we ask that you confirm your identity as a human. The spring constant shows how much force is needed to compress or extend a spring (or a piece of elastic material) by a given distance. \"https://sb\" : \"http://b\") + \".scorecardresearch.com/beacon.js\";el.parentNode.insertBefore(s, el);})();\r\n","enabled":true},{"pages":["all"],"location":"footer","script":"\r\n

Figure 2: The apparatus setup for the Hooke's . If you push the spring, however, it pushes back, and if you pull the spring, it pulls back.\r\n
Hookes law is valid as long as the elastic material youre dealing with stays elastic that is, it stays within its elastic limit. If you pull a spring too far, it loses its stretchy ability. What does this mean the spring constant should be?\r\n\r\nIn order to figure out how to calculate the spring constant, we must remember what Hookes law says:\r\n\r\nF = kx\r\n\r\nNow, we need to rework the equation so that we are calculating for the missing metric, which is the spring constant, or k. I have the question: "A mass of $10$ kg bounces up and down on a spring. Spring constant: Definition, Equation, Units, Explanation, Examples [Pdf] Asthma affects people in their different stages in life, yet it can be avoided and Why would a data analyst create a template of their .RMD file select all that apply 1 point? Frequency of the resulting SHM. In Hookes law, the negative sign on the springs force means that the force exerted by the spring opposes the springs displacement.
