Dynamic velocity units
WebSep 26, 2015 · 3) Dynamic Viscosity (η) F = ηA×SR. In the expression above (Newton’s law of viscosity), dynamic viscosity works as the proportionality constant between the stress F/A and the rate of deformation or shear rate. An alternative way to think about kinematic viscosity is to realize that it has units of diffusivity [cm 2 /s]. For this reason ... WebAbout this unit. Having a specific understanding of an object's position, acceleration, velocity, and motion comes in handy in situations ranging from bobsledding to launching rockets into outer space. Let's explore the concepts and equations that govern how objects move, and learn how to calculate the specifics of an object's motion.
