Confusing speed with velocity, neglecting the directional component of velocity. Overlooking that deceleration is still a form of acceleration (negative acceleration). Failing to correctly apply the vector …

Jul 20, 2025 · As far as I know, if we have a wave function as a sum of many momentum eigen function, i.e., ##\\psi=\\sum_k \\alpha_k e^{i(kx-\\omega t)}##, the group velocity is the velocity of the whole …

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 then multiply it by …

May 20, 2024 · The “Addition of Velocities” formula (more correctly, the “Composition of Velocities” formula) in Special Relativity v A C c = v A B c + v B C c 1 + v A B c v B C c is a non-intuitive result …

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 please …

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 magnitude of the …

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...

Mar 17, 2009 · Homework Statement A 4.80 kg object initially at rest at the origin is subjected to the time-varying force shown in the figure What is the object's velocity at t =6 s ? Homework Equations F …
