gravity deflection
1Deflection (physics) — Deflection occurs when an object hits a plane surface In physics deflection is the event where an object collides and bounces against a plane surface. In such collisions involving a sphere and a plane, the collision angle formed with the surface… …
2Gravity anomaly — A gravity anomaly is the difference between the observed gravity and a value predicted from a model. Geodesy and geophysicsIn geodesy and geophysics, the usual model is the surface of a global spheroid (ellipsoid of Hayford or WGS84) by rather… …
3Gravity 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… …
4Speed 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 …
5Vertical deflection — The vertical deflection (deflection of the plumb line, astro geodetic deflection) at a point on the earth is a measure of how far the direction of the local gravity field has been shifted by local anomalies such as nearby mountains. (Here gravity …
6Asteroid deflection strategies — are methods by which near Earth objects could be diverted, preventing potentially catastrophic impact events. A sufficiently large impact would cause massive tsunamis and/or, by placing large quantities of dust into the stratosphere blocking… …
7Earth's gravity — Earth s gravity, denoted by g , refers to the gravitational attraction that the Earth exerts on objects on or near its surface. Its strength is usually quoted in terms of the acceleration it gives to falling bodies (acceleration due to gravity),… …

10Introduction to general relativity — General relativity (GR) is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by… …
