Learn how to calculate the speed of a mass in a circular pendulum with this clear physics tutorial! Step-by-step explanations make it easy to understand circular motion, energy, and angular velocity.

A new theory proposes that the universe’s fundamental forces and particle properties may arise from the geometry of hidden extra dimensions. These dimensions could twist and evolve over time, forming ...

The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental physics. The very structure of spacetime might underlie every interaction in ...
