Analyze an uphill skier problem using work, energy, and power principles. See how gravitational potential energy, applied force, and friction determine the required work and power, and learn how speed ...

In this video, we break down the concept of the coefficient of friction in AP Physics 1, explaining how static and kinetic friction work and how they affect motion. Clear examples and reasoning help ...

From free body diagrams to energy methods, a structured approach to Mechanics can turn one of JEE’s toughest sections into a ...

How is it that quantum physics governs the very smallest things in the universe, yet classical, Newtonian rules describe the movements of everything else, from people to planets? In the second of two ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...

Microsoft’s near-term margin pressure reflects a “physics problem” of massive AI CapEx colliding with surging long-term demand. Satya Nadella’s “new economics of AI” signals a company-wide shift ...

Researchers have been looking at everything, including supernovas, trying to uncover the mysteries of dark matter. Recent scientific studies suggest that dark matter might not be a particle hiding in ...

While atmospheric turbulence is a familiar culprit of rough flights, the chaotic movement of turbulent flows remains an unsolved problem in physics. To gain insight into the system, a team of ...

Daniel Whiteson and Andy Warner’s upcoming book is a philosophical exploration of the humanity behind our desire to find aliens. Reading time 6 minutes At Gizmodo, we love a good story about ...
