Centrifugal- and Centripetal force - Physics Stack Exchange
Jan 18, 2025 · The centrifugal and centripetal forces very much do balance each other (in the rotating frame, which is the only frame where there is a centrifugal force anyway).
How does the centripetal force change when the radius changes?
May 10, 2024 · The centripetal force for a constant radius is $m\frac {v^2} {r}$, but what if that radius is changing as you're spinning the object. Say a spring with a spring constant $k$ that is being spun …
