Final answer:

Uniform circular motion involves constant speed with changing velocity direction, leading to centripetal acceleration. Examples include propeller motion.


Explanation:

Uniform circular motion describes the movement of an object traveling a circular path with constant speed. One example is a propeller spinning at a constant rate. In this type of motion, although speed remains constant, acceleration occurs due to the continuously changing direction of the object.


The centripetal acceleration is the acceleration experienced in uniform circular motion, always directed towards the center of the circle. This acceleration is caused by the centripetal force, which keeps the object moving in a circular path.


Even though the object's speed is constant, its velocity is changing because of the direction changes. This concept makes uniform circular motion an example of accelerated motion, as the object is constantly changing its velocity direction despite maintaining a constant speed.
