Equations of motion when masses move according to Newton's law of gravity. In general relativity, rotational motion is described by the relativistic angular momentum tensor, including the spin tensor, which enter the equations of motion under covariant derivatives with respect to proper time. The Mathisson–Papapetrou–Dixon equations describe the motion of spinning objects moving in a gravitational field. Unlike the equations of motion for describing particle mechanics, which are systems of coupled ordinary differential equations, the analogous equations governing the dynamics of waves and fields are always partial differential equations, since the waves or fields are functions of space and time.

Gravity: Original Motion Picture Soundtrack Gravity: Original Motion Picture Soundtrack Gravity: Original Motion Picture Soundtrack is the soundtrack album of the 3D science fiction thriller film "Gravity", written by British film composer Steven Price. The album was released in 2013 via WaterTower Music label. Price's score was universally applauded by film critics and audiences alike, leading Price to win and receive nominations for several Best Original Score awards at ceremonies, including a BAFTA Award, a Satellite Award and an Academy Award, as well as a Golden Globe Award nomination. Composer Steven Price was originally called in to help out for three weeks on the music
