Velocity - Wikipedia
Velocity is a measurement of speed in a certain direction of motion. It is a fundamental concept in kinematics, the branch of classical mechanics that
BASS XXVI: DR2 Host Galaxy Stellar Velocity Dispersions
We present new central stellar velocity dispersions for 484 Sy 1.9 and Sy 2 from the second data release of the Swift/BAT AGN Spectroscopic Survey (BASS DR2). This constitutes the largest study of velocity dispersion measurements in X-ray selected, o...
Angular acceleration - Wikipedia
physics, angular acceleration (symbol α, alpha) is the time derivative of angular velocity. Following the two types of angular velocity, spin angular velocity
Gas-dynamic acceleration of bodies till the hyper sonic velocity
The article considers an opportunity of gas-dynamic acceleration of body from the initial zero velocity till the finite velocity: five kilometers per second. When the gas flow rate of the body pre-acceleration reaches one kilometer per second, the bo...
Radial velocity comparison of Gaia DR2 and RAVE DR5 survey: a systematic offset in radial…
Here, we report comparative study of radial velocity ($\rm RV$) data of two major surveys: Gaia Data Release 2 and RAVE Data Release 5. We restricted the sample to stars with relatively accurate radial velocities ($σ_{\rm RV_{Gaia}} \leq$ 2 km s$^{-...
Radial-Velocity Monitoring of Members and Candidate Members of the TW Hydrae Association
We present our spectroscopic measurements of the radial velocity, effective temperature, and projected rotational velocity of several of the known members of the TW Hya association, as well as measurements for candidate members selected on the basi...
Acceleration - The Physics Classroom
Accelerating objects are changing their velocity - either the magnitude or the direction of the velocity. Acceleration is the rate at which they change their velocity.
The Norma Cluster (ACO 3627): I. A Dynamical Analysis of the Most Massive Cluster in the G…
A detailed dynamical analysis of the nearby rich Norma cluster (ACO 3627) is presented. From radial velocities of 296 cluster members, we find a mean velocity of 4871 +/- 54 km/s and a velocity dispersion of 925 km/s. The mean velocity of the E/S0...
Ultrafast ultrasound coded vector Doppler imaging of blood flow velocity and resistivity
Dynamic and precise measurement of cerebral blood flow velocity is crucial in neuroscience and the diagnosis of cerebrovascular diseases. Traditional color Doppler ultrasound can only measure the velocity component along the ultrasound beam, which re...
A generic rule that simplifies the derivation of the transformation equations accounting f…
We show that the transformation equation for the tardyon velocity involves two generic functions which in turn depend on the relative velocity of the involved reference frames, on the tardyon velocity u and on the polar angle which define the direc...
The Origin and Distance of the High-Velocity Cloud MI
The high-velocity, neutral hydrogen feature known as MI may be the result of a supernova that took place about 100,000 years ago at a distance of 163 pc. Low-velocity HI data show a clear cavity, a structure indicative of regions evacuated by old exp...
A Catalog of Ultra-compact High Velocity Clouds from the ALFALFA Survey: Local Group Galax…
We present a catalog of 59 ultra-compact high velocity clouds (UCHVCs) extracted from the 40% complete ALFALFA HI-line survey. The ALFALFA UCHVCs have median flux densities of 1.34 Jy km/s, median angular diameters of 10', and median velocity widths...
