The short answer is no it can't. There are a few more complex situations where you could argue the oposite: 1/ A race car doing laps around a circuit could have an average speed over 1 lap of 200mph but would have an average velocity of zero. This is because speed is a scalar measurement (how fast an object is moving) whilst velocity is a vector measurement (how fast an object is changing its position) Since the race car is at the start/finish line at the start and end of the lap it is in the same position so its average velocity is zero. Of course at any given moment during its lap its velocity would not be zero so I don't think this counts. Average velocity can be zero whilst average speed is not zero but "average" is the important word and isn't included in the question. 2/ Frames of reference - The Earth is travelling around the sun at a speed of roughly 67,000 mph (about 100,000 kph.) At what speed is a book sitting still on a table moving? If we use the Earth as a frame of reference then the book has a speed and velocity of zero. If we use the Sun as a frame of reference then the book is actually moving at a speed of about 67,000mph. (Plus or minus a bit for the rotation of the Earth about its axis.) If we use different frames of reference then a body can have zero velocity in one and non-zero speed in another. I'm inclined to think this is "cheating" and that the answer to the question remains no.
Yes, an object moving at a constant velocity has zero acceleration even though it has a non-zero velocity. For example, a car driving at a steady speed on a straight highway has a constant velocity but zero acceleration.
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 speed is the distance traveled divided by the time taken, and it is a scalar quantity. Average velocity is the displacement divided by the time taken, and it is a vector quantity that includes direction. Average speed and average velocity are only equal when an object moves in a straight line, but when there are changes in direction, they can be different.
An example problem involving speed is calculating the average speed of a car that travels 100 miles in 2 hours. An example problem involving velocity is determining the velocity of a ball thrown upward with an initial velocity of 20 m/s at a height of 40 meters above the ground.
no its a vector quantity,not a scalar quantity,bcz still it z a velocity bt NT a speed On a typical journey the average velocity is the straight-line distance between the start and finish, divided by the time taken, and it also has a direction. The average speed is the actual distance run, divided by the speed. The average speed might not be equal to the magnitude of the average velocity. For example on a round trip the average speed might be 40 mph, while the average velocity is zero.
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.
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.
Yes, an object moving at a constant velocity has zero acceleration even though it has a non-zero velocity. For example, a car driving at a steady speed on a straight highway has a constant velocity but zero acceleration.
No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0

For the instantaneous value of average velocity, average speed and average velocity are equal.
Velocity is speed and its direction. Average velocity is average speed and its direction.
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
No, it can't. Average VELOCITY can be zero, though.
Velocity is a speed with a direction (e.g. 20 miles per hour North). your example is an average velocity. velocity is displacement over elapsed time. it is speed. i know this and im only 11
Average speed is the distance traveled divided by the time taken, and it is a scalar quantity. Average velocity is the displacement divided by the time taken, and it is a vector quantity that includes direction. Average speed and average velocity are only equal when an object moves in a straight line, but when there are changes in direction, they can be different.
The correct term is velocity, not velocity.There is no reason why an object cannot have 0 velocity and 0 average speed - relative to some fixed reference point. I assume that your school, for example, has 0 velocity and 0 average speed.
