Velocity
Velocity the rate of change of position in a given direction, composed of both speed and direction (dict. Of sp. And ex. Sc. 2006, 219P.) Velocity 1. The vector describing the change in position divided by the change in time. 2. The time rate of change of position. 3. The derivative of position as a function of time. Velocity is measured in meters/second (m . S-1). See also speed (dict.Of sp.And ex.Sc.1991, 157P) velocity physical unit of measurement (denoted by the symbol v) during a uniform motion, i.E. A motion where equal distances are covered in equal time intervals. Velocity is the constant ratio of the covered distance (s) and the time (t) taken for travelling along that distance v=s/t. For non-uniform movements, which include most sport movements (especially those performed during speed competi- tions such as track and field running events, skiing, automobile and horse races), this ratio represents the average velocity. Velocity is registered in the si-unit m/sec (metres per second) or other legal units (cm/sec, m/min, km/h, etc.), In nautical sport events » knots are used (nautical miles per hour). Methods for measuring velocity in sport are (in movement analyses) cinematography and (in speed competitions) measuring time by means of a stop watch or » electronic timing devices (light beams, etc.).
