Select the situation below that would produce an average velocity of zero.?
A dog running in circles, stopping where it started
Can you have zon zero displacement and a non zero average velocity?
No.
If the average velocity of an object is zero in some time interval what can you say about the displacement of the object for that interval?
When the velocity is zero at the crossing of the time axis, the displacement must be a full maximum or minimum. Scroll down to related links and look at "Displacement - Velocity- Acceleration".
Can you have zero displacement and nonzero velocity?
i will give u an illustration, consider an object projected (thrown)with some initial vertical velocity from the ground such that it traces a open downward parabolicpath, in that path the vertical displacement of the body from the point of projection to the point where it strikes the ground is equal to zero,but it have some velocity.
What is instantaneous velocity of a body in terms of its average velocity?
The instantaneous velocity is the limit of the average velocity, as the time interval tends to zero. If you are not familiar with limits, basically you make the time interval very small and calculate the average velocity.

Can the criss-crossing path of a flying bug produce an average velocity of zero?
Yes.
What situations would produce an average velocity of zero?
This would be when you travel form one point to somewhere else and then bake again while having the same velocity when you started and when you finished.
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,
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.

Why is the average velocity of the molecules in a gas is zero but the average of the square velocity not zero?
The gas molecules are in motion but if the total gas volume is stationary (Eg. closed in a container) the average gas velocity is zero. And since the square of any number is never negative. And not all molecules have zero velocity at a time. Therefore, since not all numbers are zero and no number is negative the the average of numbers should be a positive number and will not be zero.
Why average velocity of molecules in gas zero whereas the average square of velocity is not zero?
Because squaring a velocity removes its sign. A velocity may be negative, but it's square is always positive. If two velocities are +5 and -5, their average is zero. But both squares are +25, so the average square is +25.
What is the average velocity of a tennis racquet?
The average velocity is pretty close to zero. Velocity is a vector, so its average value is the total displacement divided by the total time. Since the racquet probably starts and finishes in the player's bag in the player's home, the average velocity is zero.
Would a radio controlled car produce an average velocity of zero?
For the purposes of this explanation, velocity will be given in m/s. If it's starting position is the same as its stopping position, the radio controlled car will have an average velocity of zero meters per second. This is because average velocity is displacement/time interval. Displacement is change in position and is a vector quantity, which has magnitude and direction. Average velocity is the displacement/time interval, and is also a vector quantity, including the magnitude of the speed and its direction. If you start and stop walking at the same position, your displacement is 0m, even if you walked a distance of 100 miles, and your average velocity would be 0m/s. Refer to the related link below for an illustration.
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
