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

absolute value (magnitude) of velocity is speed. For example, "5 meters per second" is a scalar and not a vector,

whereas "5 meters per second east" is a vector. The average velocity v of an object moving through a displacement (Δx)

during a time interval (Δt) is described by the formula:

The rate of change of velocity is referred to as acceleration.
