Non-Newtonian fluids are those that ooze in some conditions and stiffen in others as they respond to forces applied to them. Newtonian fluids, by contrast, act like fluids no matter what’s done to.
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity can be conceptualized as quantifying the frictional force that arises between adjacent layers of fluid that are in relative motion. For instance, when a fluid is forced through.
A Newtonian fluid (named for Sir Isaac Newton) is always a liquid, no matter what forces are exerted on it. Water is a typical example: it doesn’t thicken or become more viscous, and poking it with a.

ketchup is a non-Newtonian fluid. Click the link below to see the brilliantly illustrated breakdown of the physics behind it, but it boils down to ketchup not behaving in a way that “normal” liquids.
“pain” “florence Nightingale” "We have known since the time of Florence Nightingale that listening to music has a positive. Exactly how and why music eases anxiety and pain is still not known. Some researchers have speculated. After getting a busy signal for 15 minutes, I finally get the orthopedic. A dulcet-toned woman who sounds like Jaclyn Smith in
Despite their exotic properties, non-newtonian fluids are pretty easy to make. A good amount of cornstarch mixed up with water will do. What’s needed is a number of particles suspended in just enough.

On their own, boring old water and cornstarch don’t seem like they’d be able to create such an interesting product. But get them together and they form a non-Newtonian fluid. To really understand.
Fluids (like water) that behave according to Newton’s model are called “Newtonian fluids.” Doubling the speed at which these layers flow past each other doubles the resisting force. In non-Newtonian.
