Dec 27, 2024 · I thought velocity was always a vector quantity, one with both magnitude and direction. When it came to the suvat equations, where v = final velocity, and u = initial velocity, …

Oct 31, 2022 · The viscous force within a fluid will depend on the velocity gradient (aka shear rate) within the fluid. That does not mean that the viscosity is a function of velocity. Viscosity is …

May 29, 2017 · Phase velocity and wave velocity are numerically equivalent, defined as ω/k, but conceptually they can represent different aspects of wave behavior. While both terms describe …

Jul 20, 2025 · Since the phase velocity is linear in , , the group velocity is an average of all the phase velocities in the wave pocket. This turns out true in the simplest case which wave …

Sep 3, 2012 · This relates to speed, not velocity. Displacement and speed are non-vector quantities, whereas position and velocity are vector quantities. It is impossible to have a …

Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time. To do this we work out the area of the nozzle and …

Jun 24, 2016 · Velocity divided by acceleration does not yield distance, as the units do not align correctly. The discussion highlights a common confusion between the symbol 's' representing …

Jul 9, 2021 · Though average speed over a finite interval of time is greater or equal to the magnitude of the average velocity, Instantaneous speed at an instant is equal to the …

Sep 19, 2010 · To find the initial velocity of an object launched at a 33-degree angle that lands 85 meters away, the correct formula is range = v0^2 * sin (2θ) / g. The calculated initial velocity is …

May 13, 2009 · Homework Statement calculate the final velocity of an object sliding across a surface with a coefficient of friction of 0.2, a distance of 3m, an initial velocity of 50m/s and the …
