Put arms narrow

Thats correct

And without bore you with Newtons Laws i just quote some "normal words"..

"as when the arms and gesture leg are à la seconde, rotation is slower since more mass further away from the body’s center of rotation. As that mass gets pulled closer to the center of rotation, conservation of angular momentum dictates that the dancer must turn faster"

Quoted from "Baltazar_Blake"

What are the main units of measure in the system (MKS)?

Meter (m), Kilogramm (kg) und Second (s).

didntz know that before, same as i dint know about 45 angle of shots or throws.
Thats why i love that Forum game that much, i really even learn things :yes:
