#rotating — Public Fediverse posts

#Rotating a #Point about the origin, through some #Angle θ is something that is taught in school #maths class, usually in #CartesianCoordinates, by multiplying the #Coordinates by a the rotation #Transformation #Matrix. What’s not generally taught is that you can apply the same transformation to any #Function y=f(x). All you need to do is replace
x by xcosθ + ysinθ
and y by -xsinθ+ysinθ.

What in the heck is the Gulf of Mexico doing? 🤔 (does it normally rotate like that?) Any tropical weather want to tell me if that's a normal thing? #TropicalWx #rotating #GulfOfMexico

#Starship 🚀 flip maneuver - #Passengers might feel some #disorientation 🤮 during the flip from #horizontal to #vertical, but the stress on their body will not be higher than what they would experience on most #RollerCoasters. #SpaceX might install #rotating seats 💺 in the future to help keep the G forces experienced on the body in only one direction https://everydayastronaut.com/starships-belly-flop-maneuver

#Physics #Science #Fun #Quiz

Scenario:

You're bored, feeling devilish and ready for some #Hijinks.

You find an unexpecting friend and perch them on a #rotating #chair.

"Up for some fun?", you ask...

Yep, they're good to go.

You instruct them to keep their arms and legs away from their body whilst you start to spin them on the chair.

Ok, they're sailing along at 90rpm (whilst suppressing the urge to vomit)

You shout, "pull your arms and legs in, now!"

They comply.

What happens next?
