the question is very simple.no a body does not have acceleration when it is moving with constant velocity ,because a body posses acceleration when its velocity is not remain conserved or constant.yes if a body have constant speed it may have acceleration but not in case of constant velocity.

when velocity of a car is increasing then velocity and acceleration are parallel to each other.

Explain circumstances, in which the velocity acceleration of a body is parallel?

Acceleration is the change in velocity over a period of time. a = v/t

When the body moves with uniform velocity its acceleration is 0. Pls explain.

Yes, you can. Zero acceleration simply means there is no CHANGE in velocity. It doesn't mean there is no velocity.

If an object has zero acceleration, its velocity doesn't have to be zero. Acceleration is a measure of the change in velocity over time. Zero acceleration means there is no change in velocity over time, namely constant velocity. Constant velocity can be any velocity (including zero velocity or "at rest"), so the object's velocity doesn't have to be zero to have zero acceleration.

Of course. A car with brakes applied and slowing down has forward velocity and rearward acceleration.

the acceleration of the car is increasind.Then the v and a are parallel to each other.

Yes, a body can have aceleration without velocity. Consider sin x the position; cos x is the velocity and -sin x is the acceleration. Here the acceleration negative when x=90 degrees and the velocity is zero at 90 degrees.

Yes. Acceleration is defined as a change in velocity, and velocity is a measure of speed AND direction. Maintaining a constant speed while rounding a corner is an example of acceleration.

Acceleration involves a change in velocity. In the case you mention, the speed doesn't change, but the velocity does. The term "velocity" includes the direction of the movement, and the direction does change.
