Jump start physics problem with a mass on a spring. This video explains the setup, key assumptions, and the step-by-step physics needed to solve for motion, energy, and forces in a spring–mass system.

In this video, we model a catenary curve using a mass-spring system, showing how a chain-like shape can emerge from discrete masses connected by springs. We connect the simulation to real physics, ...

Increasing train speeds and greater axle loads on the rail lines of today has correspondingly increased the harmful impact of noise and vibrations on the areas around rail lines. The unevenness that ...
