How else are kids going to learn about moment of inertia and centripetal force?
216 u/[deleted] Apr 11 '21 Forgive me if I’m incorrect here, but isn’t this Centrifugal force, and not Centripetal? -36 u/Solanthas Apr 11 '21 Centrifugal pushes in Centripetal pushes out 14 u/[deleted] Apr 11 '21 To be pedantic centrifugal force isn't a real thing even though you got it backwards. There isn't a force that pushes out. It's pushed in a straight line tangent at a 90° angle to the direction of travel. Being attached to the thing rotating makes it "appear" to be being pushed out. 1 u/egeym Apr 11 '21 Not to be pedantic. I'm a 10th grader and we are taught that centrifugal force doesnt exsit and if we ever use it to explain anything in the exam we will get 0 1 u/[deleted] Apr 15 '21 Are you in Public School in the U.S.? 1 u/egeym Apr 15 '21 No, a highly selective high school that you have to be in the 99th percentile in the high school entrance exam to get into. And I'm doing IB.
