- When a metal spring is stretched or compressed, it is displaced from its equilibrium position. As a result, it experiences a restoring force that tends to retract the spring back to its original position. This force is called the spring force. It is a contact force that can be found in elastic materials.

The SI unit of force is the newton (N), which is a kilogram meter per second squared (kg·m/s2). Other common units include: 1. dyne 2. kilogram-force (kilopond) 3. poundal 4. kip 5. pound-force
The Greek philosophers Aristotle and Archimedes studied force, but believed constant motion requires a constantly applied force. Galileo Galilei and Sir Isaac Newton corrected this misperception and described force mathematically. Galileo’s inclined plane experiment (1638) mathematically described naturally accelerated motion. Newton’s three laws o...
Forces exist all around us in the everyday world. For example: 1. Friction is a force that opposes motion. 2. Applied force is the force applied to an object by a person or other object. 3. Centripetal forceis a force acting on a body moving in a circular path that is directed toward the center of the circle. 4. Centrifugal forceis an apparent forc...
The four fundamental forces of nature are gravity, electromagnetism, the strong interaction, and the weak interaction. 1. Gravity is the attractive force between two masses. It acts over an infinite distance, but is the weakest of the fundamental forces. 2. Electromagnetism describes the attraction and repulsions of electrical charges and magnets. ...

ISBN 978-0-520-08817-7.The Spring force formula is given by, F = k(x – x 0) Where, the spring force is F, the equilibrium position is x o the displacement of the spring from its position at equilibrium is x, the spring constant is k. The negative sign tells that the visualized spring force is a restoring force and acts in the opposite direction. Spring Force Solved ...
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 ...
Discover the phenomena of springs and Hooke's Law. Explore how force applied to a spring results in compression or elongation, and how this relationship is linear. Uncover the concept of restorative force and how it counteracts applied force, keeping our spring in equilibrium. Created by Sal Khan.

- 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)

- 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.

Dec 22, 2020 · The law essentially describes a linear relationship between the extension of a spring and the restoring force it gives rise to in the spring; in other words, it takes twice as much force to stretch or compress a spring twice as much.
