When does the average velocity become zero?

When does the value of energy become zero for an electron?

When does the magnetic flux becomes zero ?

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.

The motion of a particle along a straight line is described by equation : x = 8 + 12 t - t^3 where x is in metre and t in second. The retardation of the particle when its velocity becomes zero is.

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.

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.

The relation between position and time f for a particle , performing one dimensional motion is as under : t = sqrt(x) +3 Here x is in metre and t is in second . (1) Find the displacement of the particle when its velocity becomes zero . (2) If a constant force acts on the particle , find the work done in first 6 second .

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.

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
