Tension forces explained through a superhero rope problem

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 ...

Beyond chemistry: How mechanical forces shape brain wiring

During brain development, neurons extend long processes called axons. Axons link different areas of the brain and carry ...

Bridging theories across physics helps reconcile controversy about thin liquid layer on icy surfaces

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 ...

Force and Motion: Tension, Spring and Resisting Forces

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...
