Angular Momentum

Magic, got it.

I can’t understand this. Another example please?

Okay, so I have this compulsive need for revolving chairs to spin equally each direction, I was so happy when he turned back the same direction, you have no idea.

That’s how villains sling around in their chairs, the secretly have fidget spinners spinning really fast

I love this clip. Angular momentum is used to turn and spin some small rockets. Very cool.

Did anyone else do this as a kid at their science center?!

This might be a dumb question, but I’ve sat in that chair before and I know it takes a (significant) force to turn that wheel sideways. Is the force exerted on that wheel equal to the “force” that causes the person to rotate? I understand the conservation of momentum concept, but is there also a conservation of forces and/or energy going on here?

There’s a science museum in Salzburg where you can try this yourself. They have a tone of practical demonstrations, it’s great for kids and adults…

There was a science tent at a Virginia state fair back around 2002, they had a spinning plate on the floor instead of a chair but same concept. The wheel used was a larger bike tire that my scrawny 6 year old arms couldn’t hold up by myself, so they hand me the tire and spin it I hold it out in front of me for about 5 seconds then lower my arms. Giving myself a pretty bad road rash all across my chest, it started bleeding and I was forced to wear a bandage around my torso for the entire next week. The Mark’s took an unusually long amount of time to heal. The moral of the story… science is evil and I’m a week dumbass.
