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.
How is average velocity of a body calculated when its velocity changes at a non-uniform rate?
average velocity=displacement/total time taken
Can particle have zero speed and non zero velocity?
No.
Can you have a zero acceleration but non zero velocity explain it with help of a graph?
Yes, you can. Zero acceleration simply means there is no CHANGE in velocity. It doesn't mean there is no velocity.
Can an object have zero velocity but still have an acceleration?
A simple example is a ball tossed into the air. When the ball reaches its apex -- its highest point -- its instantaneous velocity is zero. If we assume that up is the positive direction, the ball's velocity is positive when it is initially tossed into the air, but it slows immediately. That is, its velocity becomes less positive until it reaches zero velocity. After that point, the velocity becomes increasingly negative (because down is the negative direction). Until the ball returns to earth and reaches the height at which it was initially thrown, its average velocity is non-zero. If the ball is allowed to hit the ground, its average velocity will be slightly negative, which is still non-zero. But it still had an instant -- at its apex -- when its velocity was zero.

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,
Can particle have zero speed and non zero velocity?
No.

Yes, you can. Zero acceleration simply means there is no CHANGE in velocity. It doesn't mean there is no velocity.
Can a body have without velocity?
Yes, but it will have a non-zero velocity afterwards.

How an objects be motionless and in equilibrium?
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.

When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
Can displacement be zero even if distance is non zero?
On a three dimensional basis yes it can. Fir instance, if an object is moving directly towards or away from you the angular displacement can be zero though the distance displacement changes.
Does a body moving with uniform acceleration have momentum?
As long as it has a non-zero velocity, it will have a non-zero momentum.
What hasa zero velocity yet a non-zero acceleration?
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
