Understand tension forces through a fun superhero rope problem. This video uses a real-world–inspired scenario to explain how tension acts in a rope, how forces are distributed, and how Newton’s Laws ...

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 ice in a domestic freezer is remarkably different from the single crystals that form in snow clouds, or even those formed on a frozen pond. As temperatures drop, ice crystals can grow in a variety ...

Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, ...
