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?
No, a particle in one dimension with zero speed will have zero velocity. Velocity is a vector quantity that includes both the speed and direction of motion, so if the speed is zero, the velocity will also be zero since there is no direction of motion.
Is it possible in straight line motion a particle having zero speed and non zero velocity explain?
maybe in a black hole, an object might circle around the best space while traveling in a straight line. from an observer outside, the object would seem stationary yet have a velocity pointed radially inward to center of black hole.
Average velocity of a particle is zero but not its average speed .. is it possible?
Yes, it is possible. Average velocity takes into account both the magnitude and direction of motion, and can be zero if the particle moves back and forth. However, average speed only considers the total distance travelled over time, and can be non-zero even if the velocity is constantly changing.
A net external force acts on a particle This net force is not equal to zero is this sufficient information to conclude that the velocity of the particle changes?
Yes, if a net external force is acting on a particle, it will cause the particle's velocity to change according to Newton's second law (F=ma). The direction of the velocity change will be in the direction of the net force.

Whether an object is moving or not depends on its?
velocity or speed and direction of motion. If an object's velocity is zero, it is considered to be at rest. If an object's velocity is non-zero, it is moving.
Can a body moving with constant speed has acceleration?
Yes. Eg : in case of a uniform circular motion. In general, for every motion in which direction of motion of particle keeps changing continuously and the particle moves with same speed, then the net acceleration is non-zero, although tangential acceleration is zero.
Is it possible that there is a non-zero acceleration but with a speed of value zero?
Not with any sensible definition of "acceleration" and "velocity." You CAN accelerate an object and have it end up at zero velocity. But, if the acceleration remains a non-zero number, then the velocity can NOT remain at zero. Your question is like asking, "Can the value of a quantity change, but also remain the same?"
Can you have a zero acceleration but non zero velocity.explain with graph.?
Yes, you can have a situation where an object has a non-zero velocity but zero acceleration. This occurs when the object is moving at a constant speed in a straight line. On a velocity-time graph, this would be represented by a horizontal line at a non-zero velocity value and a flat line at zero acceleration.
Can a particle with maximum speed have zero acceleration?
Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.Yes. Velocity implies both a magnitude and a direction. An object going around in a circle moves at a constant speed, but the direction, and therefore the velocity, is changing.Yes.

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.
