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".
the displacement is zero.
Note that distance travelled would not be zero though. as velocity doesn't signify anything abt distance travelled.
speed will give you what distance you travelled.
Since average velocity is zero, some component is negetive some positive or no movement at all. whichever case may be, the displacement will be zero.
If the average velocity of a duck is zero in a given time interval, it can be said that the displacement of the duck is also zero. The duck did not leave its original position.
Average velocity is zero if the displacement is zero.
Average velocity = Displacement/Time = 0/Time = 0.
not 0
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.
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
The velocity of an object at a particular instant or at a particular point of its path is called instantaneous velocity. In another word, the instantaneous velocity of an object is defined as the limiting value of the average velocity of the object in a small time interval around that instant , when the time interval approaches zero. v = dx/dt , where dx/dt is the differential coefficient of displacement "x" w.r.t. time "t"
v = Δdt / Δt Average velocity = Total displacement / time If you want to be more specific: v = ds/dt Instantaneous velocity = derivative of displacement with regard to time
average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)

If the average velocity is 5.2 m/sec. then it means that the moving object undergoes a displacement of 5.2m in a time interval of 1 sec. along a particular direction. If the average velocity is 5.2 km/hr. then it means that the moving object undergoes a displacement of 5.2km in a time interval of 1 hr. along a particular direction. Thus depending upon the unit used, the description will be different.

It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".

i think no
yes
Any object which moves has velocity.Velocity is a vector quantity which includes direction so the object's velocity will change at every point in time if there is a nonzero acceleration.An object going around in circles uniformly will have a zero average velocity when measured as displacement over a time interval if the time interval is a multiple of the period of revolution. Speed is similar to velocity but is a scalar quantity independent of direction; you can think of it as distance covered traveling per unit of time; that is what your speedometer measures.

There is average velocity, and there is instantaneous velocity. I don't think "overall velocity" is a concept generally used in physics; please clarify what you mean.
