Figure Skating and Angular Momentum

AI Thread Summary
In figure skating, skaters can slow their rotation by spreading their arms, which affects their moment of inertia. When a skater spreads their arms, they increase their moment of inertia, leading to a decrease in angular velocity due to the conservation of angular momentum. This principle states that if no external torque acts on a system, the total angular momentum remains constant. Consequently, as the skater's arms move outward, their spinning slows down. Understanding this relationship between angular momentum and moment of inertia is crucial for analyzing skater movements.

In Figure Skating, when the players are rotating, there’s a way to slow him/herself down, do you know what’s that? Using the knowledge of angular momentum, analyze qualitatively why he/she can achieve such effect?

Key words: hand spreading, moment of inertia, conservation of angular momentum.
 
can u explain in detail how it would work, thanks

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
