Angular momentum vs. Linear momentum

Click For Summary
SUMMARY

Angular momentum and linear momentum are distinct physical quantities that do not convert into one another directly. In the example of a spinning top, when it stops, the angular momentum does not convert into linear momentum; rather, the top loses angular momentum due to friction with air and ground. The air does not pick up rotation in a way that converts angular momentum into linear momentum. Instead, the system conserves angular momentum until external forces act upon it.

Can angular momentum change into linear momentum and vice versa? For instance, when a top spins, and it stops, isn't the angular momentum converted into linear momentum from friction with air?
