Weightlessness is the experience (by people and objects) during freefall, of having no apparent weight. This condition is also known as microgravity (see below).

Amusement park rides often produce sensations of weightlessness. These sensations result when riders no longer feel an external force acting upon their bodies.

Yet, as she falls from the tower, the seat has fallen out from under her. ...
