Explore the physics behind rope swings and learn how to calculate the maximum tension in the rope using centripetal acceleration. This video breaks down the forces at play when swinging in a circular ...

Understand the physics behind Atwood’s Machine with this detailed explanation from the Feynman Lectures exercises! This video breaks down how masses, pulleys, and acceleration interact, providing a ...

CAMBRIDGE, Mass. -- A mysterious phenomenon detected by space probes has finally been explained, thanks to a massive computer simulation that was able to precisely align with details of spacecraft ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

Dark energy remains among the greatest puzzles in our understanding of the cosmos. In the standard model of cosmology called the Lambda-CDM, it is accounted for by adding a cosmological constant term ...

You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...
