No.Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement.

What is the relation between instantaneous speed and instantaneous velocity?
They are the same thing, however velocity is 'in a given direction', speed is in any direction.
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
Can the average velocity of the body be the same as instantaneous velocity?
Yes, the average velocity of the body can be same as the instantaneous velocity at a small time interval.The values of the average and the instantaneous velocities approach each other , as the length of time interval is decreased.
When an object moves with constant velocity does its average velocity during a time interval differ from its instantaneous velocity at any instant?
No. If it its moving at constant velocity, its instantaneous velocity would be the same as its constant velocity.
Can the average velocity of a body be the same as the instantaneous velocity?
Yes, but in uniform motion.
Would instantaneous velocity yield the same value as average velocity?
Only if the velocity is constant.
What is a instantaneous velocity?
Instantaneous velocity: The velocity of an object at one moment in time.
When is the average velocity equal to the instantaneous velocity?
When an object is in constant motion (when there is no acceleration). At any point in that motion the average and instantaneous velocities will be the same.
Compare and contrast velocity and instantaneous speed?
velocity is just a general term for speed (it could be average velocity or instantaneous velocity). Instantaneous velocity/speed (same thing) is the speed at that second. If you are familiar with calculus, it is the derivative of the position graph. Whereas average velocity is how fast the object is going in, for example, 1 hour, it is the speed that is maintained the whole hour (or the average) Instantaneous would be that at the second, at for example t=1.425, the speed is 24m/h . something along those lines
What is the scientific symbol for instantaneous velocity?
The symbol for instantaneous velocity is vi.
What is the Instantaneous velocity?
Instantaneous velocity is the velocity in difference displacement in shortest time or specific time interval.
Is instantaneous velocity a vector or a scalar?
Velocity is always a scalar, instantaneous or average doesn't matter.
Does the slope of a position time graph represent average velocity or rate of change of velocity?
The tangent at a point on the position-time graph represents the instantaneous velocity. 1. The tangent is the instantaneous slope. 2. Rather than "average" velocity, the slope gives you "instantaneous" velocity. The average of the instantaneous gives you average velocity.
When is the average velocity is equal to the instantaneous velocity?
At a small time interval, the average velocity is approximately equal to the instantaneous velocity. However, the values of the average velocity and the instantaneous velocity approach each other , as the length of the time interval is decreased more and more.
How is instantaneous velocity different from average velocity?
Average velocity is the average of the velocty of entire motion where as instantaneous velocity is the velocity at an instant, it may be a function of time or displacement.
When is the instantaneous velocity equal to avg velocity?
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
What does instantaneous velocity mean?
Instantaneous velocity is a vector quantity representing the velocity Vi at any point.It is the time rate of change in displacement.
Is instantaneous velocity a vector quantity?
"Velocity" is a vector quantity. This also applies to instantaneous velocity. If you want the scalar quantity, you talk about "speed".
What is the relationship between average velocity and instantaneous velocity?
The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.
Whats the difference between average velocity and instantaneous velocity?
the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object
What is the difference between instantaneous velocity and instantaneous speed?
Speed, instantaneous or not, is a term used for how fast an object travels. Velocity, instantaneous or not, is a term used for how fast an object travels in a particular direction.
You want correct formula for instantaneous velocity?
v(t) = dsdt This should be the formula for instantaneous velocity.
If the instantaneous velocity of an object is constant then so is acceleration.?
It does not make sense to say that the instantaneous velocity is constant. Instantaneous velocity by definition means that it is the velocity at a moment of time. If this is a question on some homework, just say no. The acceleration, or rate of change of the velocity, is not necessarily constant.
What is the difference between Instantaneous speed and instantaneous velocity?
Speed has only size. Velocity has size and direction.If three drivers are driving their cars at 50 mph headed north, 50 mph headed south, and50 mph headed east, their speeds are all equal, but their velocites are all different.Instantaneous speed is the speed at an instant in time. A point on the edge of an LP record hasthe same instantaneous speed whenever you look at it.Instantaneous velocity is the velocity ... speed and direction ... at an instant in time. A point on theedge of an LP record has a different instantaneous velocity every time you look at it. Even thoughthe speed is always the same, the direction keeps changing.
If the instantaneous speed of an object remains constant can its instantaneous velocity change?
Yes. Velocity is speed and direction so it can change velocity by changing direction.
