Can the average velocity of a particle be zero when its average velocity is not zero?

All experimental observations until now are in unanimous agreement that
such an event cannot occur. Within the limits of our ability to measure
the relevant quantities to date, it appears to be impossible.

Average velocity of a particle is zero but not its average speed .. is it possible?
Yes - for example, if an object moves in a circle.
Can particle have zero speed and non zero velocity?
No.
Can particle with velocity or speed at zero be accelerating?
Yes.
Can the average velocity of a particle be zero but not its average speed?
Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.
A net external force acts on a particle This net force is not equal to zero is this sufficient information to conclude that the velocity of the particle changes?
Yes. F=ma if f is non zero then a is non zero and the velocity changes if the particle is not constrained, free to move.
Can a particle in one dimensional with zero speed may have non zero velocity?
There are fundamental errors in the question. A particle is three dimentional and cannot exist in a one dimentional universe, nor can velocity.
What is particle velocity at the extreme end of vibration?
Most likely zero.
A net force acts on a particle this net force is not equal to zero is this sufficient information to conclude that the kinetic energy of the particle changes?
Yes. If the net force is not zero, the particle accelerates. Accelerate means the velocity changes,if the velocity changes the kinetic energy of the particle changes.
Can a body have nonzero average speed but have zero average velocity give example?
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
When the velocity of a particle is constant its acceleration is also constant?
Its acceleration is zero, which is constant
How is it possible for a car to have an average velocity of zero and an average speed of 65 mph?
If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.
Can you have zon zero displacement and a non zero average velocity?
No.
