High-viscosity fluids, on the other hand, behave quite differently. They flow slowly, resist deformation, and, in some cases, act more like solids than liquids, posing challenges when it comes to ...

Fluid dynamics is the branch of physics concerning fluid flow. It is distinguishable from other disciplines in fluid mechanics as it deals with fluids in motion. In physics, a fluid is a substance ...

In this video we take a look at viscosity, a key property in fluid mechanics that describes how easily a fluid will flow. But there's more too it than that! We'll start by defining viscosity using ...

Cosmologists are facing an unexpected puzzle. The latest observations do not perfectly match the mathematical model used for decades to describe the evolution of the Universe. This model, ...

New research findings show how higher viscosity, or resistance to flow, of the extracellular fluid that surrounds cells enables cancer cells to migrate more rapidly from a primary tumor to other sites ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

If you mix cornstarch and water in the right proportions, you get “oobleck”: something that seems not-quite-liquid but also not-quite-solid. Oobleck flows and settles like a liquid when untouched, but ...
