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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …
