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.

The average velocity of a particle moving on a straight line is zero in a time interval. Assertion :- It is possible that the instantaneous acceleration is never zero in the interval. Reason :- It is possible that the instantaneous velocity is never zero in the interval.

If average velocity of particle moving on a straight line is zero in a time interval, then

If average velocity of particle moving on a straight line is zero in a time interval, then

Magnitude of average velocity and speed are found to be the saame in an interval of time.

It magnitude of average speed and average velocity over an interval of time are same, then

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.

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.

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.
