Earth gravity formula

WebA gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense. Webt. e. In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction which causes mutual attraction between all things with mass or energy [clarification needed]. Gravity is, by far, the weakest of the four …
