Question

(a) a cat is able to land on its feet after a fall. Why? (b) if angular momentum moment of inertia is decreased, will its rotational k
e. . Be also conserved? Explain.

Answer 1

Answer:

If a cat is dropped they almost always tend to land on their feet because they use the conservation of angular momentum to change their orientation. ... When the cat is in the air, no net external torque acts on it about its centre of mass, so the angular momentum about the cats centre of mass cannot change.
