Is the spring force proportional to extension
John Castro
Published Mar 30, 2026
For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension doubles.
What is spring force proportional to?
The force of the spring is directly proportional to the extension of the spring. In other words, if you pull on the bob a lot, the force will be strong; if you pull on the bob a little, the force will be weak.
How forces affect the extension of a spring?
Hooke’s law states that the extension of a spring is directly proportional to the force applied, provided that the elastic limit is not exceeded. The aim of the experiment is to investigate the relationship between a force and the extension of a spring, and see if the spring obeys Hooke’s law.
What is the relationship between load and extension for the spring?
Hooke’s law of elasticity is an approximation that states that the extension of a spring is directly proportional to the load applied to it.Is spring constant proportional to length?
More generally, a spring’s spring constant is inversely proportional to the spring’s length, assuming we are talking about a specific material spring and thickness. So suppose we cut the spring exactly in two in the above example, making two shorter springs each 3 cm in length.
What is the maximum extension of the spring?
The maximum extension should be 2F/k . F/k is the extension in the spring in the equilibrium position . Maximum extension should be double of that . Work energy theorem also gives maximum extension to be 2F/k .
How do you find the extension of a spring?
- If you measure how a spring stretches (extends its length) as you apply increasing force and plot extension (e) against force (F);
- F = ke.
- F = tension acting on the spring.
- e is extension = (l-lo); l is the stretched length and lo is original length, and.
- k is the gradient of the graph above.
Do applied force and spring force act along the same direction?
Yes, spring force is always equal to the applied force, but note that it is opposite in signs because of the direction of the force.What equation links force spring constant and extension?
Hooke’s Law states that the force needed to compress or extend a spring is directly proportional to the distance you stretch it. As an equation, Hooke’s Law can be represented as F = kx, where F is the force we apply, k is the spring constant, and x is the extension of the material (typically in meters).
Is spring force constant?The force exerted by a spring on objects attached to its ends is proportional to the spring’s change in length away from its equilibrium length and is always directed towards its equilibrium position. … The proportional constant k is called the spring constant.
Article first time published onHow does force affect extension?
extension of an elastic object is directly proportional to the force applied to it. In other words: • If the force applied is doubled, the extension doubles • If no force is applied, there is no extension The graph of force against extension is a straight line through the origin, which shows a linear relationship.
What is force and extension?
Extension happens when an object increases in length, and compression happens when it decreases in length. The extension of an elastic object, such as a spring, is described by Hooke’s law: force exerted by a spring = extension × spring constant.
Does a spring obey Hooke's Law?
Hooke’s Law states that the more you deform a spring, the more force it will take to deform it further. … Because of this trait, springs that obey Hooke’s law fall into the category of “linear force” springs. The Spring Constant. The spring constant determines exactly how much force will be required to deform a spring.
How does length of spring affect spring constant?
If you stretch a spring to double its initial length, then ideally it will keep the same spring constant (although if you exceed its elastic limit you may just ruin it). If you hook two identical springs together in series, or otherwise make a double-length spring, it will have half the spring constant.
Does the spring constant depends upon length of the spring?
The spring constant will depend on the stiffness of the spring material, the thickness of the wire from which the spring is wound and, the diameter of the turns of the coil, the number of turns per unit length and the overall length of the spring.
Does a spring constant change?
Yes, spring constant do changes with cutting of the spring. Spring constant is inversely proportional to length i.e if a spring of 2 cm is cut into two equal parts then the spring constant becomes twice the initial value of spring constant.
What is a force extension graph?
Term. Explanation. Force-extension or force-elongation graph A force-extension (or force-elongation) graph is used to describe the properties of a material when in tension. It is the result of tensile testing. Extensometer An extensometer is a device that is used to measure changes in the length of an object.
What is the maximum extension for the spring in the two cases?
(a) The maximum extension of the spring in both the cases will be =F/k, where k is the spring constant of the spring used. As, this F is directed towards mean position of the mass, hence the mass attached to the spring will execute SHM.
What is maximum extension?
Maximum Extension Period means the maximum period specified in the Special Terms by which you can extend the Due Date and work with your Buyer to collect payment of an insured receivable. The Maximum Extension Period starts on the day after the Due Date.
Which law relates the force and extension of a stretched spring?
Hooke’s Law is a principle of physics that states that the that the force needed to extend or compress a spring by some distance is proportional to that distance.
How do you find the spring constant with mass and extension?
W = kx. W is the weight of the added mass. Therefore, the spring constant k is the slope of the straight line W versus x plot. Weight is mass times the acceleration of gravity or W = mg where g is about 980 cm/sec2.
Why is spring force equal to applied force?
We know that the spring force is equal and opposite to the gravitational force because the mass would otherwise be accelerated by the net force. Therefore, like gravity, a displaced spring can be regarded as a definition of an applied force.
What is the relationship between spring force and applied force?
There is a linear relationship between force applied and the extension (not displacement) of a spring. It is based on Hooke’s law. For example, if a force of 5 Newtons results in a spring extending by 10 cm, Hooke’s law says that a force of 10 Newtons will extend the spring by 20 cm.
Is spring force the same as applied force?

Why is spring force negative?
The force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium. In Hooke’s law, the negative sign on the spring’s force means that the force exerted by the spring opposes the spring’s displacement.
What is the spring force?
Spring force is the force required or exerted to compress or stretch a spring upon any object that is attached to it. When an object applies a force to a spring, then the spring applies an equal and opposite force to the object. It always acts so as to restore mass back toward its equilibrium position.
How do you increase spring force?
To increase the tension (or force) of your spring, you must either increase the wire diameter, decrease the outer diameter, or increase the length of your high tension spring’s body; therefore decreasing the .
How do you identify spring Obey's Hooke's Law?
To know if the given spring obeys Hooke’s law or not, record each stretching force in Newtons and the corresponding length of the spring. The extension is the new length minus the unloaded length.
How do you calculate the extension of a spring GCSE?
F = keF = k x ee =e = F ÷ k
What factors increase air resistance?
Falling with Air Resistance To keep the topic simple, it can be said that the two most common factors that have a direct effect upon the amount of air resistance are the speed of the object and the cross-sectional area of the object. Increased speeds result in an increased amount of air resistance.
Is force directly proportional to extension?
For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension doubles. This works until the limit of proportionality is exceeded.
