Dec 27, 2024 · Velocity is fundamentally a vector quantity, possessing both magnitude and direction, while speed is a scalar representing only magnitude. In the context of the SUVAT …

Sep 25, 2016 · The discussion centers on the relationship between the exit velocity of gas and the diameter of a hole in a pressurized container. Initially, it was suggested that the exit velocity …

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 …

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 …

Aug 1, 2009 · I heard it would be possible to have zero instantanous velocity & non zero acceleration (I know the opposite situation where there is velocity (constant), but zero …

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 …

Nov 21, 2009 · The minimum speed required for an object to complete a vertical circle is derived to be (rg)^0.5 at the top of the circle, where r is the radius and g is the acceleration due to …

Aug 15, 2017 · Velocity is made up of two components magnitude (speed) and direction. So, in the simplest case, if the magnitude changes but the direction is the same, then I would think it …

May 31, 2013 · To calculate the speed of air exiting a nozzle from a compressed air tank, the pressure ratio must be considered to determine if the flow is choked, which occurs when the …

Jul 31, 2009 · The discussion revolves around calculating the unit vector for velocity and the confusion surrounding the equations used. The initial equation presented for velocity, vel = (U …
