Final answer:
Centripetal acceleration can change the speed of circular motion by changing the direction of the velocity.
Step-by-step explanation:
Yes, centripetal acceleration can change the speed of circular motion by changing the direction of the velocity. In circular motion, the centripetal acceleration is always directed towards the center of the circle, which causes the object to continuously change its direction. As the object changes direction, it experiences a change in velocity, which is defined as speed in a particular direction. Therefore, the speed of the object in circular motion can change due to the centripetal acceleration.Centripetal acceleration alters speed of an object in circular motion by continuously redirecting its velocity towards center of the circle. This change in direction leads to a corresponding change in velocity, impacting speed of the object in circular path.
