Question

a man with a wrist watch on his hand falls from the top of a tower.does the watch give correct time during the free fall? pls xplain

Answer 1

The time shown by the wristwatch of a man falling from the top of a
tower is not affected by the fall. Since a wristwatch does not work on
the principle of a simple pendulum, it is not affected by the acceleration
due to gravity during free fall. Its working depends on spring action.

Answer 2

wow ....thanks ....reallly cleared my concepts...thanks a ton

Answer 3

the answer at the back of my book says that ' gravity disappears for man so, under free fall, frequency is zero". I understood that watch does not work on principle of simple pendulum but how can gravity disappear for man??? pls explain
