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.

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,
Is it possible to have a situation in which the speed of a particle is always zero but the average speed is not zero?
No. If the speed is always zero, then the average of its speed at any two points in time is also zero.
Is it possible for an object to move for 10 seconds at a high speed and end up with an average velocity of zero?
Yes
Is your speed is constant if you are traveling in a straight line with an acceleration of zero?
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
Why is the average velocity of the molecules in a gas is zero but the average of the square velocity not zero?
The gas molecules are in motion but if the total gas volume is stationary (Eg. closed in a container) the average gas velocity is zero. And since the square of any number is never negative. And not all molecules have zero velocity at a time. Therefore, since not all numbers are zero and no number is negative the the average of numbers should be a positive number and will not be zero.
Can particle have zero speed and non zero velocity?
No.
Average velocity of a particle is zero but not its average speed .. is it possible?
Yes - for example, if an object moves in a circle.
Can particle with velocity or speed at zero be accelerating?
Yes.
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,
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.
Is it possible to have a situation in which the speed of a particle is always zero but the average speed is not zero?
No. If the speed is always zero, then the average of its speed at any two points in time is also zero.
Is it possible in straight line motion particle have 0 speed and a non-zero velocity .explain?
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
Can a particle in one dimensional with zero speed may have non zero velocity?
There are fundamental errors in the question. A particle is three dimentional and cannot exist in a one dimentional universe, nor can velocity.
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.
Is it possible in straight line motion a particle have zero and non-zero velocity explain?
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
Can a particle with constant speed be accelerating what if it has constant velocity?
Velocity is speed together with its direction.Acceleration indicates a change in velocity ... speed or direction or both.Change of direction means acceleration, even if speed is constant.Constant velocity means constant speed and direction ... zero acceleration.
Can average speed of a moving object be zerogive an example?
No, it can't. Average VELOCITY can be zero, though.
