Howcome when we’re spinning around on an office chair with our legs sticking straight out, we can speed up by simply pulling our legs in?
In: Physics
Conservation of angular momentum. With your arms or legs outstretched they have a larger angular momentum when compared to having them tucked. If you are spinning at a certain rate with legs outstretched and you bring them in you *must* increase your rotation speed in order to keep angular momentum the same.
