Velocity is a vector (has a size and a direction) but speed is a scalar (just a number).
The velocity is therefore given by the speed and the direction the speed is going. If you change the direction but continue at the same rate the velocity changes but the speed doesn't
Yes, it is possible. If you are moving at a constant velocity, you will feel no acceleration or deceleration. In contrast, if you are not moving at all, you will feel stationary with no change in velocity.
No, it isn't possible. Velocity specifies both speed and direction; if velocity doesn't change, that means that neither the speed nor the direction change.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.

No, because acceleration is the rate of change of velocity.

since accelaration is the change in velocity of an object per unit time......if velocity is zero then there is no acceleration.its nt possible
Not necessarily. Constant velocity also means no change in direction.

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".
Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
constant speed means no acceleration and thus no change in velocity
Constant velocity means that an object is moving at a consistent speed and in a straight line, without any changes in direction. Acceleration is the rate at which velocity changes with time, so if there is no change in velocity, there is no acceleration. So, an object moving at a constant velocity does not have any acceleration.
