If the average velocity o nonzero for some time interval does this mean that the instantaneous velocity is never zero during this interval?
Not at all. Consider this example: -- I start out at 8:00 in the morning. -- I head east, drive 5 miles in 15 minutes, and park my car at 8:15. -- I go into my office, close the door, and spend the next 9-1/2 hours on Wiki.Answers. -- I leave the office exhausted at 5:45 in the evening. -- I head east again, drive another 5 miles in the next 15 minutes, and stop at a bar at 6:00. ==================================================== I left home 10 hours ago, and I am now 10 miles east of my home, enjoying a tall cold one. My average velocity for the 10 hours is 1 mile per hour east. The average is non-zero, even though I was at my desk playing computer games from 8:15 until 5:45. At any instant during 95% of the day, my instantaneous velocity was zero.
What else can I help you with?
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.
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.
Which encoding type always has a nonzero average amplitude?
Pulse-position modulation (PPM) encoding type always has a nonzero average amplitude. In PPM, the signal's average amplitude is determined by the positioning of the pulses within the signal. This ensures that there is always a nonzero amplitude level in the signal, even during silent periods.
How does the velocity of an object traveling in a straight line change if a nonzero net force acts in the same direction as the objects velocity?
If a nonzero net force acts in the same direction as the object's velocity, the object's velocity will increase over time. This is because the force accelerates the object in the same direction as its motion, causing it to speed up.
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.
Can you have a nonzero average velocity?
Yes. As long as the inital and end positions are different, you will have a nonzero average velocity.

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.
What object has velocity?
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.

How does vector calculus apply in fluid mechanics?
The velocity at each point in the fluid is a vector. If the fluid is compressible, the divergence of the velocity vector is nonzero in general. In a vortex the curl is nonzero.
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.
What is the time limited signal?
A time limited signal is one that is nonzero only for a finite length time interval.
Is it possible that a body has zero speed and nonzero velocity?
No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0
