  1. Is velocity ever a scalar quantity? - Physics Forums

    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, …

  2. Numerade

    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 …

  3. Ticker Timer Experiment: Calculating Displacement, Velocity ...

    Apr 15, 2006 · The discussion revolves around conducting a ticker timer experiment at 50 GHz to calculate displacement, average velocity, and acceleration of a trolley. Participants clarify that …
