What is the physical meaning of a negative average velocity?
It means that an object with a negative average velocity is moving in the opposite direction (of course according to the chosen positive direction of the predefined frame).
When is the average velocity is equal to the instantaneous velocity?
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
Does velocity only describes the direction in which an objects moving?
No. Velocity is a vector that describes both the direction in which an object is moving and its speed in that direction.
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
What does velocity tell you about a moving object?
Velocity tells you what speed a moving object travels at and in what direction.
What is the speed of an object moving on a particular direction?
The speed of an object moving in a particular direction is called the velocity and it's a vector, that is, it has magnitude and direction. Speed is the scalar part of velocity.
What is an average of the velocity of 5.2?
If the average velocity is 5.2 m/sec. then it means that the moving object undergoes a displacement of 5.2m in a time interval of 1 sec. along a particular direction. If the average velocity is 5.2 km/hr. then it means that the moving object undergoes a displacement of 5.2km in a time interval of 1 hr. along a particular direction. Thus depending upon the unit used, the description will be different.
How fast an object is moving in a particular direction is described as what?
velocity (distance/time)

No. Velocity is a vector that describes both the direction in which an object is moving and its speed in that direction.
Can a body moving with uniform speed have variable velocity?
Yes it can.When a body moves in a circular path keeping its speed uniform then it will have variable vilocity as vilocity is the speed in a particular direction and while moving in a circular path its direction keeps changing and so does vilocity
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
What describes both speed and direction?
Velocity describes both the speed and direction an object is moving.
What does velocity tell you about a moving object?
Velocity tells you what speed a moving object travels at and in what direction.
How is the speed of a body related to its velocity?
The speed is the MAGNITUDE of the velocity, i.e., without regard to the direction.
What describes an object and speed and direction?
As regards a moving object, we call the measure of the speed and direction it is moving its velocity.
