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.

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.

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.

Is instantaneous velocity a vector or a scalar?

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

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.

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.

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

When will the average velocity be equal to instantaneous velocity?

In uniform motion.

When will the average velocity be equl to instantaneous velocity?

In uniform motion.

How is instantaneous speed different from average speed?

BecuZ average is the same limit and the other is nesting velocity

When average velocity and average speed is equal?

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

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