Fuckin magnets
How do they work?
Tide comes in, tide comes out, You can’t explain that.
Brah just discovered conservation of angular momentum
Which is just regular conservation of momentum plus a force directing it towards some center point it oscillates around, which feels weird because you can hold a lot more of it in your hands than you normally can without that oscillation.
It’s the central pedal force
my bike doesn’t have a central pedal. how does it stay up right?
Aliens.
Magnets
Same principle as a gyroscope: a turning wheel will tend to stay perpendicular or parallel to the direction of the gravity vector because if it starts tilting away from such orientation there’s a force that pushes it back.
Also works better with bigger wheels (if I remember it correctly the effect is related to spinning momentum).
I was pretty surprised when learning Physics and they show us how to derive the formula for that (which I totally forgot since that was over 3 decades ago).
Edit: Actually the gyroscopic effetc is just a part of it. See this article
Having the pivot point (steering) for the front wheel behind it’s axle helps
A Veritasium video about the topic, if someone is actually interested: https://youtu.be/9cNmUNHSBac
Dynamic stability
Wait til anon hears about launch loops or space elevators
Momentum + Gyroscopic effect
Think of this as you inch forward until the green light with a motorcycle behind you. Just stop. Riding at 2 mph is misery.
What’s really hard is getting a 5 year old to understand this before you run out of energy from trying to hold their seat and run at the same time.
My kid screams “un-let go” at me while balancing perfectly well. She understands, she does not accept.
