STEMonstrations: Moment of Inertia

NASA Astronauts Megan McArthur and Shane Kimbrough discuss moment of inertia and its effects on rotating objects. Watch as Megan demonstrates what happens to her angular speed as she alters her moment of inertia in microgravity aboard the International Space Station.

We need a lot more from this. Just the fun and science combined in such a unique environment. Love it!

Now that is what i call a STEMONSTRATION video!

[@user-dialectic-scietist1]

Thank you, NASA. This incredible video gave to me an idea. The explanation, of Mercury's paradox behavior, is that every 400 years we have a full rotation of its perihelion. I think it is a good example of a Moment of Inertia. We know, from the view of the planet's surface, that the planet is shrinking, and this, 100%, causes in time the decrease of its moment of inertia and that means that in time the speed of spinning and the speed of the linear motion of the planet they are increased. This increase in its motions could explain, and the full rotation of its perihelion every 400 years.

Great demonstration and explanation ! Thank you 😊

Enjoyed that!

Awwww so this is a flashlight. Mine is very different 🤔🤔🤔

[@malvane8061]

Does this explain why a pulsar, roughly the size of Manhattan, spins so much more than our Sun?
