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, ...

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.

The movement of waves, patterns that carry sound, light or heat, through materials has been widely studied by physicists, as ...

Multi-ignition wildfires are not overly common. But when individual fires do converge, the consequences can be catastrophic.
