Question

The average velocity is the displacement of an object at instant time.true?

Answer 1

False

Average velocity is total displacement / total time

displacement of an object at instant time is instantaneous velocity. That is velocity at that instant. It changes in every instant.

But if the motion is uniform that is the motion is in constant velocity then velocity at all instants will be the same. The instantaneous velocity and average velocity will be equal. In this case displacement of object in instant time can also be average velocity. But this is only a special case.

Answer 2

False.
The average velocity of an object is the total displacement of the object divided by the total time elapsed. It is a measure of the overall speed and direction of the object's motion over a period of time.
Instantaneous velocity, on the other hand, is the velocity of an object at a specific point in time. It is a measure of the speed and direction of the object's motion at a single instant.
Average velocity and instantaneous velocity are not the same thing. For example, an object may have a high average velocity but a low instantaneous velocity if it slowed down at the end of its journey. Or, an object may have a low average velocity but a high instantaneous velocity if it accelerated at the end of its journey.
Here is a simple example:
A car travels 100 kilometers in 2 hours. The average velocity of the car is 50 kilometers per hour. However, the instantaneous velocity of the car may have been higher or lower than 50 kilometers per hour at any given point in time. For example, the car may have been traveling 60 kilometers per hour on the highway and 40 kilometers per hour in the city.
In conclusion, the average velocity of an object is not the same as the displacement of the object at instant time.
