  • Velocity — In physics, velocity is defined as the rate of change of position. It is a vector physical quantity; both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per second: (m/s) or ms 1. The scalar… …   Wikipedia

  • Velocity obstacle — The velocity obstacle VOAB for a robot A, with position xA, induced by another robot B, with position xB and velocity vB. In robotics and motion planning, a velocity obstacle, commonly abbreviated VO, is the set of all velocities of a robot …   Wikipedia

  • CALCULUS, DIFFERENTIAL AND INTEGRAL —    in mathematics, is the method by which we discuss the properties of continuously varying quantities. The nature of the method and the necessity for it may be indicated by a simple example; e. g. the motion of a train in a track, or the motion… …   The Nuttall Encyclopaedia

  • Limit superior and limit inferior — In mathematics, the limit inferior (also called infimum limit, liminf, inferior limit, lower limit, or inner limit) and limit superior (also called supremum limit, limsup, superior limit, upper limit, or outer limit) of a sequence can be thought… …   Wikipedia
