When a skater brings her armas in when gpinnings, she Intrasets hei (A) angular speed. (B) angular momenturl. (C) Both of these. (D) Norie of these.

When a skater pulls her arms in while spinning, she is effectively reducing her moment of inertia, which causes her angular speed to increase due to the conservation of angular momentum. It’s like a magical trick of physics – the tighter you hold, the faster you go! In the realm of figure skating, this principle isn't just a cool stunt; it’s essential for mastering spins and jumps. Skaters train rigorously to perfect their technique, often practicing in front of mirrors to observe their form, making the connection between physics and artistry a delightful dance on ice!
