What happens when you double the force on a spring?
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. When an elastic object is stretched beyond its limit of proportionality, the object does not return to its original length when the force is removed.
What happens to extension if you double the force?
Hooke’s Law says that the extension of an elastic object is directly proportional to the force applied to it. if the force applied is doubled, the extension doubles. if no force is applied, there is no extension.
How do you calculate an extension of a force?
When an object, such as a spring, is stretched, the increased length is called its extension….Force on a spring.
| F = ke | F = k x e |
|---|---|
| e = | e = F ÷ k |
What is extension force?
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. This is when: force is measured in newtons (N)
Why are two forces needed to stretch a spring?
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. Work needs to be done to stretch the spring and this is stored in the spring as elastic potential energy .
What happens when spring is stretched?
When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position. The force a spring exerts is a restoring force, it acts to restore the spring to its equilibrium length.
What happens to the extension of a spring when the force acting on it is doubled?
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 force does a spring have?
restoring force
When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position. The force a spring exerts is a restoring force, it acts to restore the spring to its equilibrium length.
How do you calculate spring constant from force and extension?
As per the Hooke’s Law, if spring is stretched, the force exerted is proportional to the increase in length from the equilibrium length. The formula to calculate the spring constant is as follows: k= -F/x, where k is the spring constant. F is the force and x is the change in spring’s 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 .
