Step-by-step solution

In uniform circular motion, the particle moves with a constant speed. Thus, speed is a constant scalar. The direction of motion changes continuously along the circular path, meaning the velocity vector changes its direction at every point. Hence, velocity is a changing vector. Tangential acceleration is the rate of change of speed. Since speed is constant, the tangential acceleration is zero, making it a zero vector. Angular velocity is given by the right-hand thumb rule and points along the axis of rotation. In un
