In one-dimensional kinematics, objects with a constant speed have zero acceleration. To see this, we must analyze the motion in terms of vectors. It is remarkable that points on these rotating objects are actually accelerating, although the rotation rate is a constant. Other examples are the second, minute, and hour hands of a watch. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. Evaluate centripetal and tangential acceleration in nonuniform circular motion, and find the total acceleration vector.Explain the differences between centripetal acceleration and tangential acceleration resulting from nonuniform circular motion. ![]()
