In physics, Hooke's law is an empirical law which states that the force ( F) needed to extend or compress a spring by some distance ( x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness ), and x is small compared to the total possible ...
A esto se le conoce como la ley de Hooke, y comúnmente la escribimos así: F = − k x. Donde F es la fuerza, x la longitud de la extensión o compresión, según el caso, y k es una constante de proporcionalidad conocida como constante de resorte, que generalmente está en N / m .
Hooke's law. When studying springs and elasticity, the 17ᵗʰ century physicist Robert Hooke noticed that the stress vs strain curve for many materials has a linear region. Within certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring.
- nominal length = original/initial length
- It just tells us that the exerted by the spring will be in the opposite direction to the force applied.
- It varies between spring to spring, depending on what it is made of, the shape of the spring, and the width of the wire.
- gravity won't change the rigidity of the spring, so I think it is the same on other planets
- The nominal length is 50m. But the spring is being extended not compressed and therefore, the formula is L = Li + x= 50 mm +50 mm = 100 mm
- The spring has some length when it is relaxed, right? That's the initial length.
- I think we are only interested in the absolute value. You need not include the negative sign.
- Hooke's law doesn't say that the constant k is negative. The negative sign is only saying that the force is in the opposite direction of the displa...
- I think you're confused as to the difference between gravitational force and potential energy. Close enough to the Earth's surface, we always feel...
Hooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load.

30 de sept. de 2021 · What is Hooke’s Law. Hooke’s law states that for small displacement or deformations of an object, the displacement or deformation is directly proportional to the applied force or load. Hooke’s law can explain many mechanical properties and the strength of elastic materials.
In mechanics (physics), Hooke’s law is an approximation of the response of elastic (i.e., springlike) bodies. It states: the extension of a spring is in direct proportion with the load applied to it. For instance, the spring is pulled downwards with either no load, F p, or twice F p.
Una gráfica muestra la fuerza aplicada versus deformación x para un sistema que puede ser descrito por la ley de Hooke. El trabajo realizado en el sistema es la fuerza multiplicada por la distancia, que es igual al área bajo la curva, o 12kx2 1 2 k x 2 (Método A en la figura).
