After searching for more physics about cats this morning, I stumbled upon an article addressing this pressing question: "If you strapped a slice of buttered bread to the back of a cat, which way down would it land?" According to the writer, the equally unbreakable laws of butterology (butter must hit the ground) and feline aerodynamics (the cat must land on its feet) would both hold true and a state of floating equilibrium would be reached. Though this phony physics is all too easy to disprove, it does open some doors into the actual laws of butterology and feline aerodynamics. Physics.org asserts that toast lands butter side down because the average work surface is just high enough to allow the toast one half rotation before it bites the dust. This seems to be the accepted logic, because if toast was slid off a table, the front end would dip down and the toast could easily begin its rotation. However, Mythbusters decided that when dropped from midair toast does not have a landing preference. As for cats, their remarkable tendency to land feet first stems from their natural ability to twist themselves to a face first position without ever changing their net angular momentum according to wikipedia. They accomplish this by bending their incredibly flexible backbones so that their front half and rear half rotate about different axis. They then tuck in their front legs to reduce the front half's moment of inertia (resistance to change in rotation) and extending their back legs to increase the back half's moment of inertia. This allows the front half to rotate as much as 90 degrees in one direction while the back half rotates as little as 10 degrees in the opposite direction. Given sufficient time to repeat this process enough to turn themselves fully, the cat will always land on its feet. Plus, a cat's light bone structure and fluffiness make it's terminal velocity just 60 mph, which seems awful fast until compared with that of the standard human- 130 mph.
