Ever wonder why some objects flip when they spin?🤔 The Intermediate Axis Theorem is the answer! Watch as Astronaut Sultan Al Neyadi demonstrates this principle in microgravity🧑‍🚀 When the moments of inertia around the first (I1) and third (I3) axes are nearly equal, rotational instability around the middle axis (I2) slows, resulting in that unique flipping behavior💫 Credit: Sultan Al Neyadi via X ♫˚.⋆⭒.˚⋆ ⋆♫˚.⋆⭒.˚⋆ ⋆♫˚.⋆⭒.˚⋆ ⋆♫ #WeBelieveInAstronauts #NationalAstronautDay #AstronautsDay #NAS

The Dzhanibekov Effect, also known as the “tennis racket theorem”, is a fascinating phenomenon in rotational dynamics that was first observed in detail by Russian cosmonaut Vladimir Dzhanibekov in 1985 while aboard the Soviet space station Salyut 7. The effect describes a curious behavior seen when an asymmetrical object with three distinct moments of inertia is spun around its intermediate axis in a microgravity environment. In some cases it may also be observed in a gravitational field however
