Question

explain velocity and its types ? explain with one example

Answer 1

The velocity of an object is the rate of changeof its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion (e.g. 60 km/h to the north). Velocity is an important concept in kinematics, the branch of classical mechanicsthat describes the motion of bodies.

hope you're satisfied from that answers

Answer 2

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. ... 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.
