That's because of ketchup's physics. Ketchup is something scientists call a non-Newtonian fluid. Shampoo, mayonnaise and toothpaste are other examples of non-Newtonian fluids. Newtonian fluids— like water and oil— have a single viscosity. Thus, they always flow in the same manner. But non-...
Viscosity is a measure of a fluid's resistance to flow and is caused by the internal resistance to motion. A liquid with low viscosity, like water, flows easily compared to one with high viscosity, like honey. In general, viscosity for a liquid decreases as temperature increases. Honey, for...
Also, the energy dissipation ratios – a measure for the plasticity of the gel – were determined as a function of strain. The ALB-RF gel showed an increase in plastic response at larger strains compared to the GLB-RF gel (40% and 10% strain, respectively). ALB-F, PPC and GLB-RF ...
