Can average speed of a body can be zero explain?

Can the average speed of a moving body be zero Explain?

Yes, when it comes back to the starting point.

Can the average speed of a body be zero and can the average velocity of a moving body be zero?

Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.

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.

Can the average speed of a moving body be zero.explain?

no it cannot be zero as the formula for average speed is total distance/total time . if we will come back to the starting point also then also there is distance covered . so it cannot be zero.

Can average speed of a moving object be zerogive an example?

No, it can't. Average VELOCITY can be zero, though.

When is average veloctiy zero while the average speed is non-zero?

in circular motion

Is it possible to have a situation in which the speed of a particle is always zero but the average speed is not zero?

Yes, it is possible. For example, if a particle moves back and forth between two points with different speeds, such that the time spent at each point is unequal, the average speed would not be zero even though the particle's speed is zero at each point.

When will a body have zero speed?

yes it is possible to get a zero speed 4 a body but nly whn the universe come to a stand still n gravity will b zero...........................

Can a body have zero average velocity but a nonzero average speed give example?

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.

Is it possible for a body to have average speed but zero average velocity give reason and example?

Yes it is possible. If a body goes round a circular path then distance covered by one full rotation will be 2 pi r But the total displacement is 0. Hence the average speed exists but average velocity does not exist.

Can the average velocity of a particle be zero but not its average speed?

Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.

How is it possible for a car to have an average velocity of zero and an average speed of 65 mph?

If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.
