So the object is stopped, as it would be on solid surface. What makes non-Newtonian fluids unique is viscosity. Viscosity is the rate at which fluid flows. Common fluids, like water, have a ...

It's a perfect example of a non-Newtonian fluid - a substance that doesn't follow Newton's law of viscosity, meaning its thickness changes depending on how much force you apply to it. Most liquids, ...

These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature.
