In an homage to the short film Powers of Ten, the music video for "Gravity" features a single, unbroken take of the singer strolling in the middle of a street while people are walking behind her bringing lights, balloons, and globes of other planets representing a journey through the solar system and into deep space.^[8][9] The video was directed by Mathew Cullen of Motion Theory.^[10]

A shipping video featuring a clip montage of the characters Annie and Jeff set to "Gravity" was made by a Community fan in November 2009, halfway through the first season of the show.^[14] The video inspired show creator Dan Harmon^[15] and he included a similar sequence of clips of the two characters in the second season episode "Paradigms of Human Memory". Dan Harmon paid for the rights to the song himself. The clips of Annie and Jeff were immediately followed by clips of the characters Pierce and Abed again set to "Gravity", as a parody to show how easy it is make any set of characters appear romantically interested in one another (this was repeated with Annie's Boobs, a monkey, and the character Chang near the end of the episode). Bareilles eventually made an appearance as a hot-air balloon guide in "Intro to Felt Surrogacy", the ninth episode of the series' fourth season.

It was used as the closing song in the pilot episode of the Starz series Gravity.
