Question

If instead the puck were initially closer to the disk, as shown at right, would the magnitude of the angular momentum be greater than, less than, or equal to that in the original situation? Explain. If instead the puck were initially closer to the top of the page as shown, would the magnitude of the angular momentum be greater than, less than, or equal to that in the original situation? Explain. If instead the puck were more massive, would the magnitude of the angular momentum be greater than, less than, or equal to that in the original situation? Explain. Suppose that the puck were both closer to the top of the page as shown and twice as massive. Would the magnitude of the angular momentum be greater than, less than, or equal to that in the original situation? Explain.

Explanation / Answer

a. v is greater so angular momentum is greater

b.angular momentum is same because perpendicular distance between velocity vector and point is constant

c..angular momentum is less because perpendicular distance between velocity vectorand point is less

d.greater due to increase in mass

e. is same distance decresed by half and mass increased by double so constant
