# Newtonian Dynamics

Newtonian dynamics is really a mathematical model whose goal would be to predict the motions of the numerous objects which we experience around us. The overall principles of the model had been first enunciated by Sir Isaac Newton inside a work entitled Philosophiae Naturalis Principia Mathematica (Mathematical Principles regarding Natural Philosophy) Newtonian dynamics begins through a set of terms which are not defined within the method. In this instance, the essential terms are usually mass, placement, time, as well as force. It's assumed that we determine what these terms suggest as well as moreover, which they match a measurable quantity.

## Modified Newtonian Dynamics

Modified Newtonian dynamics (MOND) can be a hypothesis which suggests a modification associated with Newton's law of gravity to describe the galaxy rotation problem. If the uniform velocity regarding rotation of galaxies was initially observed, it had been unpredicted because Newtonian theory regarding gravity predicts which objects which are farther out may have lower velocities. As an example, planets within the Solar System orbit along with velocities which reduce as their distance from the Sun raises.

MOND has been proposed through Mordehai Milgrom in 1983 in order to model this noticed uniform velocity data. Milgrom mentioned that Newton's law regarding gravitational force continues to be verified only exactly where gravitational Speed is large.

## Mond Modified Newtonian Dynamics

Milgrom (1983) has been the first in order to suggest the modification of Newtonian dynamics (MOND) to be able to explain observations which the scientific community claims reveal the reputation of a weakly communicating, enormous, non-luminous issue (dark matter). In their paper, he designed MOND as well as referred to how it might explain numerous observational laws. First of all, we review its description regarding both the Tully-Fisher law which a galaxy's mass M as well as the rotational velocity V tend to be related by M / V
in which 4|and also regarding the rotation shape of galaxies, which they are usually asymptotically at large radii through their respective centers.

## Non Newtonian Fluid Dynamics

The non-Newtonian fluid is actually a fluid whose flow qualities vary in any method coming from those of Newtonian fluids. Most frequently the viscosity regarding non-Newtonian fluids is actually not independent of shear rate or perhaps shear rate historical past. However, presently there are some non-Newtonian fluids along with shear-independent viscosity, which nonetheless show normal stress-differences or even other non-Newtonian behavior. Several polymer solutions as well as smelted polymers are usually Non-Newtonian fluids, because there are many commonly found substances for example ketchup, custard, tooth paste, starch suspensions, shampoo, paint and also blood.
