Stokes law contains a term equal to six pi times this force times a sphere's radius times its velocity.
Instruments called rheometers measure this force. Isaac Newton stated this force times the velocity gradient in the perpendicular direction equals the shear stress. Stokes law contains a term equal to six pi times this force times a sphere's radius times its velocity. This force is accounted for in the denominator of Reynolds number and is variable in non-Newtonian fluids. There are dynamic and kinematic forms of this property; the dynamic form is expressed as mass divided by length multiplied by time, where one Pascal second is equal to ten poise. For 10 points, name this force that describes a fluid's resistance to movement
