The direction of acceleration in uniform circular motion is along the

In uniform circular motion, an object moves along a circular path at a constant speed. While the speed remains constant, the velocity vector is continuously changing because its direction is always tangent to the circle at any given point. Acceleration is defined as the rate of change of velocity. In this specific motion, the change in velocity points directly toward the center of the circle. This is known as centripetal or radial acceleration. Because the velocity vector is tangential and the acceleration vector is radial (pointing toward the center), the acceleration is always perpendicular to the velocity. This creates a right angle (90°) between the two vectors, ensuring that only the direction of motion changes while the magnitude of velocity remains constant.
