Learn how to apply the momentum principle to find the net force on a turning car! This physics tutorial breaks down the calculations and concepts step by step, helping you understand forces, momentum, ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

Explore how forces and friction work to hold a block against a vertical wall. This video explains normal force, frictional force, and equilibrium conditions, showing how these forces balance to ...

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

Researchers have achieved quantum "alchemy" that allows them to alter the properties of materials using high-powered ...

Recent integrative approaches suggest that physics cannot be adequately characterized by magnitude-based distinctions alone, such as those implied by Big-P, little-p, and mini-p physics. While these ...

A new picture of the interstellar comet 3I/ATLAS has caused a lot of surprise and confusion among scientists. This comet is special because it came from outside our solar system, and only two such ...

The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development. Sip a glass of wine, and you ...

(The Center Square) – A planned relocation of Normal’s Fire Station 2 sparks statewide concern over slow emergency response times, as a new bill at the statehouse would create a task force to ...
