Gravity assist — In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist or swing by is the use of the relative movement and gravity of a planet or other celestial body to alter the path and speed of a spacecraft, typically in… … Wikipedia
Gravity train — [ free falls through a section of the planet to arrive at a destination on the other side.] A gravity train is a theoretical means of transportation intended to go between two points on the surface of a sphere, following a straight tunnel that… … Wikipedia
Gravity turn — A gravity turn or zero lift turn is a maneuver (see trajectory optimization) used in launching a spacecraft into, or descending from, an orbit around a celestial body such as a planet or a moon. This launch trajectory offers two main advantages… … Wikipedia
Speed of gravity — In the context of classical theories of gravitation, the speed of gravity refers to the speed at which a gravitational field propagates. This is the speed at which changes in the distribution of energy and momentum result in noticeable changes in … Wikipedia
Gauss' law for gravity — In physics, Gauss law for gravity, also known as Gauss flux theorem for gravity, is a law of physics which is essentially equivalent to Newton s law of universal gravitation. Its form is mathematically similar to Gauss law for electricity; in… … Wikipedia
