Whey average velocity of electron at time tis zero?

Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

When the velocity is constant, can the average velocity over any time interval differ from instantaneous velocity at any instant? If so, give an example, if not explain why. (AS_(2) )

The velocity-time graph of a car moving along a straight road is shown in figure. The average velocity of the car in first 25 seconds is

Statement-I : A particle moves in a straight line with constant acceleration. The average velocity of this particle cannot be zero in any time interval. Statement-II : For a particle moving in straight line with constant acceleration, the average velocity in a time interval is (u+v)/(2) , where u and v are initial and final velocity of the particle of the given time interval.

Which among average speed and average velocity can be positive, negative or zero ?

Assertion :- The displacement always equals the product of the average velocity and the time interval. Reason :- The average velocity always equals the mean value of the initial and final velocities.

A particle moves in a straight line with a uniform acceleration a. Initial velocity of the particle is zero. Find the average velocity of the particle in first 's' distance.

A particle moves along x-axis with acceleration a = a0 (1 – t// T) where a_(0) and T are constants if velocity at t = 0 is zero then find the average velocity from t = 0 to the time when a = 0.

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