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
Trajectory of a projectile — In physics, the ballistic trajectory of a projectile is the path that a thrown or launched projectile will take under the action of gravity, neglecting all other forces, such as friction from air resistance, or propulsion under the influence of… … Wikipedia
Free-fall time — The free fall time is the characteristic time that would take a body to collapse under its own gravitational attraction, if no other forces existed to oppose the collapse. As such, it plays a fundamental role in setting the timescale for a wide… … Wikipedia
Gravity tractor — A Gravity tractor (GT) is a spacecraft that deflects another object in space, typically a potentially hazardous asteroid that might impact Earth, without physically contacting it, using only its gravitational field to transmit the required… … Wikipedia
