Sagot :

Final answer:

Uniform circular motion involves constant speed but changing direction, leading to acceleration.


Explanation:

Uniform circular motion involves an object traveling in a circular path at a constant speed. Although the speed is constant, the object is constantly changing direction, resulting in an acceleration. For example, when a car moves around a roundabout at a steady speed, it experiences acceleration due to the change in direction.
