Doubling the time a given average torque acts changes the change in angular momentum to:
ATwice as large
BHalf as large
CExactly the same
DDown to zero
Answer & Solution
Correct answer: A. Twice as large
1. Angular impulse is a product of two factors.
2. The change in angular momentum is given by a product.
3. That product is the average torque and the time interval.
4. Doubling one factor while holding the other fixed doubles the product.
5. So the change in angular momentum becomes twice as large.
