For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Master the concepts of average velocity and position update in this physics tutorial. Learn step-by-step how to calculate motion, update positions over time, and solve related problems with clarity.

Learn how to calculate gravitational forces on a spacecraft from Earth and the Moon! Step-by-step physics tutorial covering force equations, vectors, and practical examples for orbital mechanics.

Abstract: A class of 66 students enrolled for the first year engineering is introduced to solving numerical problems and conceptual questions in engineering physics using collaborative learning (CL), ...

Abstract: Based on the computational framework of physics-informed neural networks (PINNs), an unsupervised deep learning method is developed for inverse problems, which features good accuracy, high ...
