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.
Linear Velocity Definition. The velocity or the linear velocity of an object is the time rate of change of linear displacement of the object. It is also defined as the speed of an object in a given direction. The linear velocity can be of two types depending on the motion in which it is evolved: Uniform Velocity: An object is said to be moving with a uniform velocity if it undergoes equal displacements in equal interval of time howsoever small these intervals may be.
