Write definition of instantaneous velocity

In Exercises 3.13 and 3.14, we have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity. The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

The instantaneous speed of a body can be measured:-

Why instantaneous velocity is defined ?

A particle is projected with a speed v and an angle theta to the horizontal. After a time t, the magnitude of the instantaneous velocity is equal to the magnitude of the average velocity from 0 to t. Find t.

The instantaneous speed of the point of contact during rolling is zero.

When an average velocity of a particle becomes its instantaneous velocity ?

Assertion: Average speed of a particle in a given time interval is never less than the magnitude of the average velocity. Reason: The magnitude of the velocity (instantaneous velocity) of a particle is equal to its speed.

How do you measure instantaneous speed? (AS_(1))
