The tidal force or tide-generating force is the net force of all gravitational pull on a body and its counter acting inertia. The pull differs throughout the gravitational field which the body is in, causing the body to stretch and lag, bending towards the net gravity, as well as away with its motion, producing tidal phenomena in the body.
The most common example of tides is the tidal force around a spherical body (e.g., a planet or a moon). Here we compute the tidal tensor for the gravitational field outside an isolated spherically symmetric massive object. According to Newton's gravitational law, the acceleration a at a distance r from a central mass m is
Mathematically, the tidal force in general relativity is described by the Riemann curvature tensor, [1] and the trajectory of an object solely under the influence of gravity is called a geodesic. The geodesic deviation equation relates the Riemann curvature tensor to the relative acceleration of two neighboring geodesics.
The central force is then, of course, zero. A small force remains towards the right, directed rightwards. A small force, directed leftwards, remains at the left. This is why (perhaps somewhat counter-intuitively) tidal forces lead to a bulge on both sides of the smaller planet. Date: 20 October 2009: Source: File:Tidal-forces.png: Author
Comet Shoemaker–Levy 9 was disintegrated by the tidal forces of Jupiter into a string of smaller bodies in 1992, before colliding with the planet in 1994. The Roche limit typically applies to a satellite's disintegrating due to tidal forces induced by its primary, the body around which it orbits. Parts of the satellite that are closer to the ...
Texas officials try to intercept sale of surplus border wall materials Patrick noted that Texas became aware of the materials slated for auction on Dec. 12, the same day the Daily Wire reported ...
Tides are generated as a result of gravitational attraction by the Sun and Moon. [8] This gravitational attraction results in a tidal force that acts on the ocean. [8] The ocean reacts to this external forcing by generating, in particular relevant for describing tidal behaviour, Kelvin waves and Poincaré waves (also known as Sverdrup waves). [8]
