The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

I have already indirectly talked about this before, but I see it more and more. Say you have a show. It has to be more than entertaining, it has to educational. How do you make things educational?

To see physics in action in everyday life, look no further than figure skating. And as the men hit the ice to show off their spins and combinations Tuesday in the Winter Olympics, here's a perfect ...

The questions in this quiz are suitable for GCSE physics students studying momentum calculations, conservation of momentum and force and momentum. If you struggled with the quiz, don't panic - we've ...

It's impossible to talk about football these days without talking about the problem of big hits. The giant dramatic collisions between players moving at high speed are at once one of the great ...

Tools can change not only how theorists calculate but also what they calculate about. But two decades ago, Ursula Klein, a scholar from the Max Planck Institute for the History of Science in Berlin, ...

Electrons flowing swiftly across the surface of topological insulators (TIs) are "spin polarized," their spin and momentum locked. The potential to control electron distribution in spintronic devices ...
