what do you mean by velocity

Answer:

Step-by-step explanation:
It is how fast an object is moving. Velocity, by definition, is a vector quantity that indicates distance per time and direction. ... Velocity measures displacement over time, as opposed to distance. Acceleration is defined in technical terms as a vector quantity that indicates the rate
Answer: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.
Step-by-step explanation:
Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.
Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object has a changing velocity and is said to be undergoing an acceleration.
