displacement velocity
1Displacement (vector) — Displacement versus distance traveled along a path. A displacement is the shortest distance from the initial to the final position of a point P[1]. Thus, it is the length of an imaginary straight path, typically distinct from the path actually… …
2Displacement thickness — is the distance by which a surface would have to be moved parallel to itself towards the reference plane in an ideal fluid stream of velocity u 0 to give the same mass flow as occurs between the surface and the reference plane in a real fluid.In… …
3Velocity — 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… …
4velocity — 1) a vector quantity equal to the rate that position changes with time 2) velocity of a point in a vibrating system is the time rate of change of its displacement. ambient wind velocity forward velocity impact velocity lateral velocity… …
5Displacement receiver — A displacement receiver is a device that responds to or is sensitive to directed distance (displacement). Examples of displacement receivers include carbon microphones, strain gauges, and pressure sensors or force sensors, which, to within an… …
6Angular displacement — of a body is the angle in radians (degrees, revolutions) through which a point or line has been rotated in a specified sense about a specified axis.When an object rotates about its axis, the motion cannot simply be analyzed as a particle, since… …
7Particle velocity — is the velocity v of a particle (real or imagined) in a medium as it transmits a wave. In many cases this is a longitudinal wave of pressure as with sound, but it can also be a transverse wave as with the vibration of a taut string. When applied… …
8Threshold displacement energy — The threshold displacement energy Td is the minimum kinetic energy that an atom in a solid needs to be permanently displaced from its lattice site to a defect position. It is also known as displacement threshold energy or just displacement energy …
9Angular velocity — Do not confuse with angular frequency The unit for angular velocity is rad/s.In physics, the angular velocity is a vector quantity (more precisely, a pseudovector) which specifies the angular speed, and axis about which an object is rotating. The …
10angular velocity — Physics. the time rate of change of angular position of a rotating body, usually expressed in radians per second or radians per minute. [1810 20] * * * time rate at which an object rotates, or revolves, about an axis, or at which the angular… …
