A skater is rotating with his arms outstretched. When a skater draws his arms toward his body, his angular velocity (decreases, increases).
Pick the right answer in the parentheses
Decreases.
This is due to the conservation of angular momentum. When the skater draws his arms toward his body, his moment of inertia decreases, which means his angular velocity must also decrease in order to conserve angular momentum.
AAAaannndd the bot gets it wrong yet again!
clearly has never watched a skater.
