When a particle moves with constant velocity, its average velocity, its instantaneous velocityi and its speed are all equal. Comment on this statement.

Assertion: When a particle moves with constant velocity its average velocity, its insttantaneous velocity and its speed are all equal in magnitude. Reason: If the average velocity of a particle moving on a straight line is zero in a time interval, then it is possible that the instantaneous velocity is never zero in the internal.

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

Statement-I : If two particles, moving with constant velocities are to meet, the relative velocity must be along the line joining the two particles. Statement-II : Relative velocity means motion of one particle as viewed from the other.

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: In successive time intervals if the average velocities of a particle are equal then the particle must be moving with constant velocity. Reason: When a particle moves with uniform velocity, its displacement always increases with time.

For particle moving on circular path with constant speed angle between instantaneous velocity and instantaneous acceleration will be …... .

A particle starts from rest with constant acceleration. The ratio of space-average velocity to the time average velocity is :-

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) )

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.

A charged particle would continue to move with a constant velocity in a region wherein,
