a rate of change of position in relation to time
The rate at which an object moves. In other words, how far an object moves in a given amount of time (usually meters/sec in physics). Wave velocity is the rate that waves propagate through a medium and is affected by the medium. You can measure the velocity of waves by measuring how far a waves moves and dividing this by the time the wave takes to move that distance. Back to Wave Index

The rate of change of movement measured in metres/second (m/s) in metric. Ground vibrations are usually measured in terms of the velocity of a particular point on the ground.

The movement is said to be elastic and doesn?t result in any permanent movement.

The rate of change of position of an object, that is the speed at which it travels. Velocity (v) is a vector quantity, because it is expressed in both magnitude (size) and direction of travel. The unit of velocity is metres per second (ms-1) and can be calculated using displacement (s) and time elapsed (t) as follows: V = s/t.
