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.
Velocity describes the speed and direction of an object. Speed tells how fast an object moves, but velocity is a vector measurement and includes both the rate and direction of an object's change of... Velocity describes the speed and direction of an object. Speed tells how fast an object moves, but velocity is a vector measurement and includes both the rate and direction of an object's change of position. The formula for calculating speed is distance traveled divided by time traveled.
