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. Velocity is equivalent to a specification of an object's speed and direction of motion.

Answer:
What is Velocity?
The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time. It might sound complicated but velocity is basically speeding in a specific direction. It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity. The SI unit of it is meter per second (ms-1) if there is a change in magnitude or the direction in the velocity of a body the body is said to be accelerating.
Example of Velocity
To understand the concept of instantaneous velocity and average velocity, let’s take this example. Jewel goes to school in her dad’s car every morning. Her school is 8 km from her home, and she takes 15 mins to travel, but when she looks at the speedometer on the dashboard of the car, it shows a different reading all the time.
Well, the average velocity of Jewel’s car could be found by:
For convenience, we have considered the car to move in a straight line, and we will convert all the units of time to hours. Therefore, 15 mins = 1560 = 0.25 hours.
Average velocity, v = △x△t
v = 8 km/0.25 hrs
v = 32 km/h
Now we see that even though the car may vary its speed if it covers the same amount of distance in the same amount of time, every time its average velocity will remain the same.
