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, ...
