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.

An international group of researchers has found that chiral phonons can create orbital current without needing magnetic elements – in part because chiral phonons have their own magnetic moments.

Professor Jiawen Chen and Associate Researcher Yan Wang from South China Normal University, in collaboration with Professor ...

Engineers reinvent the 5,000-year-old gear using fluids instead of solid teeth.

Scientists at New York University and NYU Shanghai have developed a new kind of gear that works without teeth or direct ...

The theory that gravitons lose energy thru gravitational redshift while traveling against the force of a gravitational field ...

Earth’s Rotation Day, observed on January 8, marks Léon Foucault’s 1851 pendulum experiment proving Earth’s rotation. Know its history and significance.

Some historians claim that Isaac Newton had already formulated the categories in the Principia twenty years earlier. This is based on two extant documents (1664–1665 and 1669). Derek Whiteside claims ...

Abstract: The hanger reflex is an illusion phenomenon that induces strong force perception and rotational motion, and it occurs in multiple parts of the body. A potential application of this ...

Abstract: This work investigates the impact of motion estimation errors on passive inverse synthetic aperture radar (ISAR) images of rotating targets when the backprojection algorithm (BPA) is ...

In this video, we explore the fascinating world of circular motion and how forces and momentum work when objects change direction. From roller coasters to planets in orbit, discover how centripetal ...
