There are fundamental errors in the question.
A particle is three dimentional and cannot exist in a one dimentional universe, nor can velocity.
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
Yes, a particle can have a velocity of zero and still be accelerating if its speed is changing. Acceleration is the rate at which the velocity of an object changes over time, so even if the particle's velocity is momentarily zero, if it is changing, it is experiencing acceleration.
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..
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".
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.

When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
No, a particle cannot accelerate if its speed is constant. Acceleration is the rate of change of velocity, and if the speed (magnitude of velocity) remains constant, then the acceleration is zero.

Momentum = (mass) x (velocity)If the particle is at rest, velocity = 0, and momentum = 0.
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.
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.
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.
