Which statement accurately describes the velocity of a particle in uniform circular motion?

In uniform circular motion, a particle travels along a circular path at a constant speed. Although the magnitude of the velocity (the speed) remains constant, the direction of the velocity vector is continuously changing as the particle moves along the circular path. This change in direction means that the velocity vector is constantly altering, even though the speed does not increase or decrease. As a result, the particle is experiencing centripetal acceleration, which is directed towards the center of the circle, representing the ongoing change in the direction of the velocity.

The statements related to constant magnitude and unchanging velocity do not apply because even though the speed remains the same, the direction is in constant flux, which is crucial for understanding motion in a circular path. The statement about the velocity vector pointing radially outward is also incorrect in this context, as the vector actually points tangentially to the path of motion at any given point rather than directly outward from the center of the circle. Thus, the accurate description of the velocity of a particle in uniform circular motion is that it is constantly changing directions.
