Newtonianism

Example:Ketchup is a non-Newtonian fluid that becomes more fluid when it is agitated, like when you shake the bottle.

Definition:A fluid that exhibits properties inconsistent with the simple fluid models predicted by Newtonian mechanics, such as shear thinning or shear thickening behavior.

Example:The predictions of relativistic physics may differ significantly from those of Newtonian physics, especially as speeds approach the speed of light.

Definition:The branch of physics that deals with phenomena involving objects moving at speeds close to the speed of light, negating the principles of Newtonian mechanics.
