Applications of inertia

A wet umbrella is rotated vigorously and then stops abruptly. Droplets of water on the umbrella are spun off because its inertia causes them to continue moving even when the umbrella has stopped spinning.

The head of a hammer can be slotted into the hammer by knocking the bottom of the handle downwards on a hard surface. The hammer head will continue with its downward motion after the handle has come to a stop. This makes the upper part of the wooden handle slot deeper into the hammer head.
