    A cat is able to land on its feet after a fall. Why?

    Answer:

                    When a cat falls to ground from a height, it stretches its body along with the tail so that its moment of inertia becomes high. Since \[I\,\omega \] is to remain constant, the value of angular speed \[\omega \] decreases and therefore the cat is able to land on the ground gently.
