Springs
Springs are objects in physics that can compress and stretch. A spring’s equilibrium point is the length of the spring without any forces acting on the spring. When a spring stretches or compresses, the spring will exert a force in the direction of this equilibrium point. Spring force is represented with the variable Fs. This force can be described with Hooke’s Law, as seen below.
- represents the spring force
- represents the spring constant
- represents the displacement of the spring, with stretching being positive and compressing being negative
A spring’s spring constant is a value that represents the “ stiffness ” of a spring. Spring constant is measured in units of Newtons per meter (N/m) and is represented with the variable . A higher spring constant will show a stiffer spring while a lower spring constant will show a softer spring.
