For an object of volume x and velocity v, it's momentum will increase at a rate directly proportional to p (density). This is because: mass = density/volume read more
The momentum and position operators are related by the Heisenberg uncertainty principle. In continuous systems such as electromagnetic fields, fluids and deformable bodies, a momentum density can be defined, and a continuum version of the conservation of momentum leads to equations such as the Navier–Stokes equations for fluids or the Cauchy momentum equation for deformable solids or fluids. read more
Density and viscosity are not related to each other.Liquids which are having similar densities may have very different viscosities. A liquid that is dense does not necessarily have to be viscous, and the opposite is also true. For example, honey is viscous than saline water, but it is not as dense. read more
