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 else can I help you with?
If displacement is not changing as a function of time then what can we say about velocity?
If displacement is not changing as a function of time, then velocity is zero. Velocity is the rate of change of displacement with respect to time, so if there is no change in displacement, the velocity is zero.
Can a situation exist in which an object has zero acceleration and nonzero velocity even for an instant?
No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
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.
If displacement is decreasing then velocity is?
If displacement is decreasing, then velocity can be positive, negative, or zero, depending on the direction of motion. If the object is moving in the positive direction, a decreasing displacement may result in a positive velocity. If the object is moving in the negative direction, a decreasing displacement may lead to a negative velocity. If the object is stationary and its displacement is decreasing, the velocity is zero.
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 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.

If displacement is not changing as a function of time, then velocity is zero. Velocity is the rate of change of displacement with respect to time, so if there is no change in displacement, the velocity is zero.

No, if an object has zero acceleration, its velocity cannot be changing. If the velocity is nonzero, it must either be increasing or decreasing, which requires acceleration.
Can a body have zero velocity with nonzero accelaration?
Yes, but only for an instant.
Can an object have zero velocity and nonzero acceleration?
Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.
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.

If displacement is decreasing, then velocity can be positive, negative, or zero, depending on the direction of motion. If the object is moving in the positive direction, a decreasing displacement may result in a positive velocity. If the object is moving in the negative direction, a decreasing displacement may lead to a negative velocity. If the object is stationary and its displacement is decreasing, the velocity is 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".
When are the displacement velocity and acceleration equal to zero for the motion of a mass on a spring?
Displacement and acceleration are zero at the instant the mass passes through its "rest" position ... the place where it sits motionless when it's not bouncing. Velocity is zero at the extremes of the bounce ... where the expansion and compression of the spring are maximum, and the mass reverses its direction of motion.
What is the condition of the position-time graph when the velocity-time graph passes through zero?
As, in the velocity-time graph, curves passes through zero means 'when time is zero velocity is zero'. Velocity is time derivative of displacement. So displacement is maximum or minimum when time is zero in position-time graph.
Do you agree with the statement an object with a zero velocity can have an acceleration greater than zero do you agree?
Yes. If it weren't so, an object that isn't moving could never be made to move at all! Of course, once you apply acceleration (which implies a change of velocity), the object's velocity won't stay zero. But for a brief instant, the velocity can be zero while accelerating.
When a vibration is at maximum displacement what is its velocity?
Zero. That's the instant at which its velocity changes direction. In order to do that, its magnitude has to be zero at that point in time.
