The displacement of an object is its Volume.
Average Velocity
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 speed of an object is its rate of displacement. Specifically, it is the rate of displacement over time or the first derivative of displacement with respect to time.
a=dv/dt average velocity = displacement divided by time take. so average velocity = displacement/time taken.

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.
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.
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
Instantaneous velocity is the velocity in difference displacement in shortest time or specific time interval.
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"
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.
