Dec 11, 2020 · Learn what spring force is, how to calculate it using Hooke's law, and see some examples of spring force in everyday life. Find out how to measure the spring constant and the work done by the spring force.
Mar 12, 2024 · These forces remove mechanical energy from the system, gradually reducing the motion until the ruler comes to rest. The simplest oscillations occur when the restoring force is directly proportional to displacement. This is called Hooke’s law force, or spring force: \[F=-k x. \nonumber \]
Learn how to calculate the force exerted by a spring using Hooke's law, which states that the force is proportional to the extension or compression of the spring. Explore examples, exercises and the concept of Young's modulus.
- 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...
Learn how force applied to a spring results in compression or elongation, and how this relationship is linear. Explore the concept of restorative force and how it counteracts applied force, keeping our spring in equilibrium.

- The equilibrium position of the string minimizes the potential energy of the metal atoms from which the spring is constructed. I don't know how muc...
- Elastomers are polymers that are designed to be highly elastic (they can stretch far without breaking). For example, yoga pants, running tights, ny...
- K is a constant that represents the elasticity of a spring (and therefore stiffness). It varies between spring to spring, depending on what it is m...
- Sal is right. If k has a big value, you will have to apply a huge force to cause a small displacement. But that also means (k having a big value) t...
- x is the displacement of the spring's end from its equilibrium point - how much the spring is stretched (or, in the other direction, compressed)
- great point. yes, usually we have 'mass-less' springs... ie their mass is very very small compared to the mass being suspended by the springs. OR w...
- I believe you mean U = k*x^2/2. This is equivalent to Hooke's law. (U is potential energy stored by spring device)
- F = kx. What MUST the units of k be if x is in meters and F has to be in Newtons? That's how constants work.
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, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of ...
