FIRST ANSWER IS THE CORRECT ANSWER Sect. 4.3 1. A body's angular momentum depends on its mass, its tangential velocity, and 2. (1) its distance from the point it is moving around 3. (2) the inverse square of its distance from the point it is moving around 4. (3) the square of its distance from the point it is moving around 5. (4) NVA 6. (5) NVA 7. 8. 9. In the definition of angular momentum, the "tangential velocity" referred to 10. is 11. (1) the part of the body's velocity that is perpendicular to the radius 12. (2) the part of the body's velocity that is parallel to the radius 13. (3) the velocity of the tangent 14. (4) NVA 15. (5) NVA 16. 17. 18. 19. A body's angular momentum depends on its mass, its distance from the origin 20. (point it's going around), and its 21. (1) tangential velocity

(1) is conserved 31. (2) slowly decreases 32. (3) disappears 33. (4) NVA 34. (5) NVA 35. 36. 37. 38. In the case of the spinning ice skater, angular momentum conservation makes 39. her spin faster when she pulls her arms in because 40. (1) it effectively decreases the distance of some of her mass, so her spin must 41. speed up 42. (2) it effectively increases her mass (over her skates), so her spin must speed up 43. (3) it effectively increases her mass (over her skates), which reduces the 44. friction and lets her spin faster 45. (4) NVA 46. (5) NVA 47. 48....
