The purpose of the two studies presented in this paper is to establish validity evidence for the Sport Multidimensional Perfectionism Scale-2 (Sport-MPS-2: Gotwals & Dunn, 2009). Studies 1 and 2 are respectively focused on the production of structurally-related and external validity evidence.
The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
An upward vertical velocity of just 6 centimeters per second can produce a large volume of precipitation if the moisture is present to be condensed. Let's apply upward vertical velocity to interpreting the synoptic scale forecast models (NAM,GFS etc.). Upward vertical velocity is plotted on the 700-mb prog. Go ahead and look at a 700 mb forecast panel on your computer. This prog is available on UNISYS weather at: You will see a panel full of colors, wind vectors, and height contours. The colors are the upward and downward vertical velocities.
