Q. An example of angular momentum conservation is

कोणीय संवेग संरक्षण का एक उदाहरण है

A
A pendulum swinging
एक पेंडुलम झूल रहा है
B
A diver curling during a dive
गोता लगाते समय एक गोताखोर कर्लिंग करता हुआ
C
A block sliding
एक ब्लॉक फिसल रहा है
D
A car moving straight
एक कार सीधी चल रही है

Explanation

When a diver curls their body during a dive, they reduce their moment of inertia. Because angular momentum is conserved (in the absence of external torque), the diver spins faster when curled and slower when stretched out. This is a classic example of angular momentum conservation. A pendulum swings but mainly involves linear motion, a block sliding involves linear momentum, and a car moving straight primarily involves linear momentum.
