Oct 31, 2022 · hello, I read in a lecture paper about fluid mechanics that velocity is not related to viscosity, i found this odd and i think it is an error , can someone...

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...

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

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 …

Feb 13, 2017 · The discussion focuses on deriving the maximum velocity of an object moving in a vertical circle attached to a string, specifically at the bottom of the path where maximum …

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 …

Dec 16, 2004 · The discussion centers on the relationship between velocity and kinetic energy, specifically why doubling the velocity of an object results in a fourfold increase in kinetic …

Jul 20, 2025 · The discussion centers on the concepts of phase velocity and group velocity in wave functions, specifically in the context of quantum mechanics. The group velocity is defined …

Sep 3, 2012 · I understand that it's possible to have a negative instantaneous velocity, but I'm wondering if it's possible to have an negative average velocity. For example, let's say you start …
