# When is the instantaneous velocity equal to avg velocity?

###### Wiki User

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.

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.

When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.

For the instantaneous value of average velocity, average speed and average velocity are equal.

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.

Instantaneous velocity: The velocity of an object at one moment in time.

That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.

Instantaneous velocity is the velocity in difference displacement in shortest time or specific time interval.

If the velocity is constant (i.e., there is no acceleration). Terminal velocity is an example, although any constant velocity would fit this description.

Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.

Velocity is always a scalar, instantaneous or average doesn't matter.

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.

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.

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.

Instantaneous velocity is a vector quantity representing the velocity Vi at any point.It is the time rate of change in displacement.

"Velocity" is a vector quantity. This also applies to instantaneous velocity. If you want the scalar quantity, you talk about "speed".

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.

the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object

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.

v(t) = dsdt This should be the formula for instantaneous velocity.

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.

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.
