20 maj 2024 · We introduce a one-dimensional coordinate system to describe the position of the mass, such that the x axis is co-linear with the motion, the origin is located where the spring is at rest, and the positive direction corresponds to the spring being extended. This “spring-mass system” is illustrated in Figure 13.1.1.

- Vertical Spring-mass System
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 ...

The force needed to stretch or compress a spring is proportional to its change in length. This is known as Hooke's law and it works for many spring-like things.
Review the key concepts, equations, and skills for spring potential energy and Hooke's law. Understand how to analyze a spring force vs. displacement graph.
Equations of motion: Solve by decoupling method (add 1 and 2 and subtract 2 from 1). As before, we can write down the normal coordinates, call them q1 and q2. which means... Substituting gives: Gives normal frequencies of: Centre of Mass. Relative.
