It has zero acceleration!!
An object moving with uniform acceleration has a uniform change in velocity over time, and its velocity-time graph will be a straight line with either a positive or negative slope. An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.
Let us suppose that the displacement is given by, x = kt2 , where k is constant of proportionality. Therefore, velocity of the body, v = dx/dt = d(kt2)/dt = 2kt Since, velocity depends on time ,the body is not moving with uniform velocity.... Again, acceleration of the body, a = dv/dt = d(2kt)/dt = 2k As the acceleration is independent of time , the body is moving with uniform acceleration..
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
As long as it has a non-zero velocity, it will have a non-zero momentum.
as direction is changing
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
For velocity to be truly uniform, the object must be moving in a straight line. If that is the case then the acceleration is Zero.
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.

Acceleration is (delta velocity) / (delta time), that is, change in velocity per time unit. In this case, since the velocity doesn't change, the acceleration is zero.
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
One feels the changes in velocity, or acceleration, when the motion of the vehicle changes.
zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
