  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...

  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. Addition of Velocities (Velocity Composition) in Special Relativity

    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 …

  5. Finding Velocity given x and y velocities • Physics Forums

    Oct 26, 2008 · 1. How do you find the velocity of an object if you are given the x and y components of the velocity? 2. Not sure! 3. It makes the most sense...

  6. Speed of sound wave and particle velocity • Physics Forums

    Nov 7, 2013 · This may be fairly straightforward but it is a concept that I am really having problems understanding. A sound wave is a pressure disturbance that travels through a …

  7. Finding the velocity at the top of a loop • Physics Forums

    Jun 17, 2014 · Hey Guys. I've been spending the last 1½ week trying to figure this out on my own, but I just can't find the answer. A car (toy car) weights at about 0,062 Kg, and enters the loop …

  8. Can force be expressed as mass flow rate times velocity

    Aug 1, 2015 · I know that F=ma which give the units of kg.m/s/s (in SI units) but can force also be expressed as mass flow rate times velocity which also has the same units? Example: water …

  9. Exit velocity of a gas through a hole - Physics Forums

    Sep 25, 2016 · Hello, Given: A large pressurized container with a small hole in a side. The sides of the container are VERY thin such that the thickness of the sides can be ignored. The …

  10. The elevator E shown in the figure moves downward with a …

    Jul 3, 2020 · Constant velocity refers to an object moving at an unchanging speed in a fixed direction. In problems involving constant velocity, acceleration is zero, which simplifies the …
