# Change in centripetal acceleration from change in linear velocity and radius: Worked examples

A worked example finding the change in centripetal acceleration from the change in linear speed, and an example finding the change in centripetal acceleration from the change in radius.

• I understand how to tackle these problems, it's fairly straightforward. However, I started this course (College Phyiscs 1) from the beginning and, no, we did not derive the formulas for centripetal acceleration (whether using linear speed or angular) in previous videos. But I hope I'll see those videos, wherever they are. I really think this particular course needs to be organized better so that we are asked questions that we've actually been prepared for.
• Why the formulas of Centripetal Acceleration for the the Question 1 and 2 different?
• They both lead to the same answer, but the formula you use depend on what information you're missing.
• At , why would you answer the question saying the second centripetal force's magnitude decreases by a factor of nine, instead of saying the second centripetal force's magnitude decreases by a factor of 1/9?
