Question

define velocity. states its unique​

Answer 1

Answer:

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.The velocity is the time rate of change of displacement. If 'S' is the displacement of an object in some time 'T', then the velocity is equal to, v = S/T. The units of velocity are m/s or km/hr.The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s). Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude.
