Answer 1

Velocity is a measure of how fast something moves in a particular direction. To define it needs both magnitude and direction. If an object moves east at 9 metres per second (9m/s), then its velocity is 9 m/s to the east Speed is one part of velocity, direction is the other part.

Answer 2

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.Velocity is a physical vector quantity; both magnitude and direction are needed to define it.
