An object moves with uniform velocity when its speed and direction remain constant. In the case of linear motion, the angle at which an object moves with uniform velocity would be 0 degrees or 180 degrees, depending on the frame of reference.
If an object is moving in a straight line with constant speed, it has a uniform velocity, and the angle with respect to its initial direction would be 0 degrees. This indicates that the object is moving directly forward or backward without deviating to the left or right.
However, if we consider circular motion, an object moving in a perfect circle at a constant speed would have a uniform velocity, but its direction is continuously changing. In this case, we cannot assign a fixed angle to the object's motion because it is constantly curving.
Therefore, the concept of an angle at which an object moves with uniform velocity depends on the type of motion being considered. In linear motion, the angle would be 0 degrees, while in circular motion, the concept of a single angle is not applicable due to continuous change in direction.
