A round-trip to school and back
A person walks forward for 2 hours and then walks back for 2 hours, ending up at the same position where they started. Their average velocity would be zero since they covered the same distance in each direction.
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.
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".

An example of average velocity of zero is when an object moves in a full circle and returns to its starting point within a given time interval. Since the displacement is zero (starting and ending at the same point), the average velocity is also zero.
Yes.

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.
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.

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.
An example of average velocity of zero is when an object moves in a full circle and returns to its starting point within a given time interval. Since the displacement is zero (starting and ending at the same point), the average velocity is also zero.
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.
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.
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.
