Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken.

As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is 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


Difference between instantaneous and average velocity?

Average velocity is simply displacement over time. Instantaneous velocity is the velocity at any given instant, or the displacement over an infinitely small amount of time.


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.


What is the Instantaneous velocity?

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


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.


Difference between average velocity and instantaneous velocity?

average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)


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.


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.


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.


Is instantaneous velocity a vector or a scalar?

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


When average velocity and average speed is equal?

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


When an object moves with inconstant velocity does its average velocity differ from its instantaneous velocity?

Generally it is a Yes. Instantaneous velocity is the exact velocity at a particular time in the course of the movement. However, average velocity is the average of all the instantaneous velocity over a period of time. It is also known as speed in everyday life. As a result, the movement of an object over a time period under varying velocity denotes a varying instantaneous velocity which could be different from the average velocity. It is however, possible that the instantaneous velocity equates to the average velocity at a certain point over the duration of movement. For example, a ball is traveling at instantaneous velocity of 99m/s at t=1s , 100m/s at t=2s and 101m/s at t=3s. the average velocity over the 3s period is hence 100m/s which coincides with the instantaneous speed at t=2s.


When Velocity of particle equals average velocity equals instantaneous equals speed is possible?

When the length of the time is decreased more and more ,average velocity of the particles equals instantaneous velocity.


What Is the difference between velocity and average velocity?

Velocity is an instantaneous measure. Mathematically, it is the limiting value of the change in the position vector divided by the change in time as the latter tends to zero. Over larger time periods, the average velocity is the total change in the position vector divided by the total change in time. If velocity is constant, the average velocity will be the same as the instantaneous velocity.


What is instantaneous velocity of a body in terms of its average velocity?

The instantaneous velocity is the limit of the average velocity, as the time interval tends to zero. If you are not familiar with limits, basically you make the time interval very small and calculate the average velocity.


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.


Are instantaneous velocity and velocity the same thing?

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.


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 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.


Under what conditions is average velocity equal to instantaneous velocity?

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.


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.


How does average velocity differ from instsntaneous 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.
