You can find out how long a spring has been stretched/compressed by knowing it's elastic constant and the force the spring is exerting trying to go back to it's original shape.
F=K*x (Moore's law)
F is the force exerted by the spring.
K is the elastic constant.
X is the displacement of the end of the spring from it's normal position.
You want to find x, x = F/K
The amount the spring is stretched is called the displacement.
Elastic potential energy is stored in a stretched spring. When the spring is compressed or stretched, it gains potential energy that can be released when the spring returns to its original shape.
When a spring is stretched beyond its limit, it reaches a point where it can no longer return to its original shape. This is known as the spring's elastic limit. If the spring is stretched beyond this limit, it will permanently deform or even break.
The amount the spring is stretched is called the displacement.
The work done by a spring when it is compressed or stretched is the energy stored in the spring due to the deformation. This energy is potential energy that can be released when the spring returns to its original shape.
F = - k x In this equation, x is the distance that the spring has been stretched or compressed away from its equilibrium position F is the restoring force exerted by the spring. k is the spring constant.
The two forces involved in a stretched spring are the restoring force, which acts to bring the spring back to its equilibrium position, and the applied force, which is the external force that stretches the spring.
When a spring is stretched, the atoms within the spring rearrange themselves to accommodate the added force. This results in an increase in potential energy stored within the spring due to the stretching. The spring exerts an equal and opposite force in an attempt to return to its natural position, causing it to behave like a restoring force when stretched.
If you take a long spring/slinkie, and stretch across a table or the floor by holding it at either end and making a quick up down movement with your arm you can send a wave down the slinkie. The height of the wave can be determined by the power of the shake I hope this helps, it was demonstated in Physics to us
The spring displacement equation is given by x F/k, where x is the distance the spring is stretched or compressed from its equilibrium position, F is the force applied to the spring, and k is the spring constant.
The spring has been stretched. When the coils are squeezed together then the spring has been compressed.
The work done by the stretching body is equal to the difference in potential energy stored in the spring before and after it is stretched. This work is done against the restoring force of the spring.
