Can the average velocity of a moving body be zero. state example?
Yes, if, for example, a car races around a circuit, its total displacement is zero and so its velocity, at the end of every lap, is zero.
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.
When is average speed of an object not equal to average velocity?
For example, an object goes in a circle, at a speed of 50 km/hour. The average speed is 50 km/hour; the average velocity is zero.
Can you have zon zero displacement and a non zero average velocity?
No.
Can an object have zero velocity but still have an acceleration?
A simple example is a ball tossed into the air. When the ball reaches its apex -- its highest point -- its instantaneous velocity is zero. If we assume that up is the positive direction, the ball's velocity is positive when it is initially tossed into the air, but it slows immediately. That is, its velocity becomes less positive until it reaches zero velocity. After that point, the velocity becomes increasingly negative (because down is the negative direction). Until the ball returns to earth and reaches the height at which it was initially thrown, its average velocity is non-zero. If the ball is allowed to hit the ground, its average velocity will be slightly negative, which is still non-zero. But it still had an instant -- at its apex -- when its velocity was zero.
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,
Can the average velocity of a moving body be zero. state example?
Yes, if, for example, a car races around a circuit, its total displacement is zero and so its velocity, at the end of every lap, is zero.
Is it possible for the average velocity of an object to be zero during some interval even thought its average velocity for the first half of the interval is not zero explain and cite an example?
i think no

yes
Can average speed of a moving object be zerogive an example?
No, it can't. Average VELOCITY can be zero, though.

Yes - for example, if an object moves in a circle.
Can average velocity of moving body be zero?
Yes; for example, an object moving in a circle.
Can the average speed of a body be zero and can the average velocity of a moving body be zero?
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
When is average speed of an object not equal to average velocity?
For example, an object goes in a circle, at a speed of 50 km/hour. The average speed is 50 km/hour; the average velocity is zero.
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.
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.
