A simple model for it might be to assume it is a #linear #viscous fluid offering resistance proportional to the velocity of the projectile, i.e. R = -k.v, where v is the velocity vector and k is a constant which dictates how viscous the fluid is.

Happily, this model has exact solutions so I didn’t need to do any numerical integration. Here are four different cases, including the ideal case k = 0. The others are k = 0.1, 1 and 10, with the k=1highlighted. Pt2...

What is the scientific word for a Fluid or semi-Fluid that holds its bead when put on a surface. Think ketchup. You could write with it, and the ketchup would mostly hold its location and height.

Is this viscosity also? Or is there a word for the vertical strength of a liquid/gel

Loving the auto-error of #AOC and #Pelosi comments being "viscous". Pretty sure you meant "#Viscous" there 😂
