4Gravity 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… …
5Gravity 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… …
6Gravity drag — In astrodynamics and rocketry, gravity drag (or gravity losses) is the difference between the delta v expended and the actual change in speed achieved by a spacecraft thrusting while in a gravitational field.Gravity losses depend on the time over …
7Gravity railroad — A Gravity railroad (US) or Gravity railway (UK) is a railroad on a slope that allow cars carrying minerals or passengers to coast down the slope by the force of gravity alone. The cars are then hauled back up the slope using animal power or a… …
8Gravity wave — In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two media (e.g. the atmosphere or ocean) which has the restoring force of gravity or buoyancy.When a fluid parcel is displaced on an interface or… …
9Gravity current — In fluid dynamics, a gravity current is a primarily horizontal flow in a gravitational field that is driven by a density difference, hence gravity currents also sometimes being referred to as density currents . Typically, the density difference… …
