Question

Why do i spin faster when i tuck my arms in when I'm skating?

Answer 1

It's like when your on a swing and you spin around you go faster than if you spread your legs out so if you bring them in you will go faster.

Answer 2

When you are spinning you are using centripetal gravity. With your body as a "core" you spin fastest with your arms tucked in because if they are not they cause drag or wind resistance.

Answer 3

This is the physics principle of conservation of angular momentum. This formula indicates one important physical consequence of angular momentum: because the above formula can be rearranged to give v = L/(mr) and L is a constant for an isolated system, the velocity v and the separation r are inversely correlated. Thus, conservation of angular momentum demands that a decrease in the separation r be accompanied by an increase in the velocity v, and vice versa. This important concept carries over to more complicated systems: generally, for rotating bodies, if their radii decrease they must spin faster in order to conserve angular momentum. This concept is familiar intuitively to the ice skater who spins faster when the arms are drawn in, and slower when the arms are extended; although most ice skaters don't think about it explictly, this method of spin control is nothing but an invocation of the law of angular momentum conservation.

Answer 4

all to do with gravity the tighter you tuck your arms and elbows in the faster you will spin try spinning with arms in and then stick them out and see how slow you will go then bring them back in and the faster you go, central gravitational force.

Answer 5

Less air resistance I guess.

Answer 6

centrifugal force.

the tighter you pull in your arms the faster you'll spin.
