Can the average velocity of a moving body be zero. state example?
Yes, the average velocity of a moving body can be zero. For example, if an object moves to the right for a certain distance and then returns back to its original position in the same amount of time, the total displacement would be zero, resulting in an average velocity of zero.
What would produce an average velocity of zero?
A round-trip to school and back
Average velocity of a particle is zero but not its average speed .. is it possible?
Yes, it is possible. Average velocity takes into account both the magnitude and direction of motion, and can be zero if the particle moves back and forth. However, average speed only considers the total distance travelled over time, and can be non-zero even if the velocity is constantly changing.
What is the average velocity of a particle when it returns to the straight point?
The average velocity of a particle when it returns to the starting point is zero. This is because velocity is a vector quantity that includes both magnitude and direction, and returning to the starting point means the displacement is zero, resulting in an average velocity of zero.
Can you have zon zero displacement and a non zero average velocity?
Yes, it is possible to have zero displacement and a non-zero average velocity. This can occur if an object moves back and forth over a certain distance so that the total displacement is zero, but the average velocity is non-zero due to the object covering distance in both directions.
Can the average velocity of a moving body be zero. state example?
Yes, the average velocity of a moving body can be zero. For example, if an object moves to the right for a certain distance and then returns back to its original position in the same amount of time, the total displacement would be zero, resulting in an average velocity of zero.
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
Can average speed of a moving object be zerogive an example?
No, it can't. Average VELOCITY can be zero, though.
Can average velocity of moving body be zero?
Yes; for example, an object moving in a circle.
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 reexplain and cite an example?
Yes, it is possible for the average velocity of an object to be zero during a given interval even if its average velocity for the first half of the interval is not zero. This can occur when the object moves in opposite directions such that the distances traveled cancel out over the entire interval. For example, if an object moves 3 meters to the right and then 3 meters to the left in equal times, its average velocity for the entire interval would be zero.
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.

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?
Yes, it is possible for the average velocity of an object to be zero during some interval, even if its average velocity for the first half of the interval is not zero. This can occur if the object moves in opposite directions with equal distances during the two halves of the interval. For example, if a car moves 3 miles east in the first half of an hour and then moves 3 miles west in the second half of an hour, its average velocity for the entire hour would be zero.
Can a body in motion can never have zero average velocity?
While a body in motion cannot have zero average velocity, there are many examples where the average velocity - after selected intervals - is zero. For example: a pendulum, or any object under simple harmonic motion, after a complete number of cycles; a rotating object (point on a wheel or hand of a clock) after a whole number of circuits.
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.
Average velocity of a particle is zero but not its average speed .. is it possible?
Yes, it is possible. Average velocity takes into account both the magnitude and direction of motion, and can be zero if the particle moves back and forth. However, average speed only considers the total distance travelled over time, and can be non-zero even if the velocity is constantly changing.
Why average velocity of molecules of a gas is zero but the square of average velocity is not zero?
It depends on the sign of velocities. For example, if there are two velocities 7 and -7 m/s then the average velocity of the molecules will be 0. But, the square will be 49. The general thing here is that even if a velocity is negative, the square of EVERY velocity irrespective of the sign is positive i.e., squaring always removes the negative sign.
