It is generally said that centripetal acceleration is directed towards the center of the circular path along the radius. So can we say that centripetal acceleration is a linear acceleration. Is it or can it be represented along a straight line. I had a question in my exams. A kid is rotating a stone tied to a rope in a constant speed and question is 'Is there linear acceleration, and why?' So can centripetal acceleration precisely be described as a linear acceleration. What is the correct answer. Also if there is change in the speed in which child rotating it what will be the direction of the net acceleration?
