Encyclopedia > Tidal friction

Tidal friction is a process that transferes energy between the planets. Io, a moon of Jupiter, is the second most volcanicaly active body in the solar system, second to Earth. This is because the gravitational forces stretches and pulls on Io, heating up its interia. This is known as Tidal friction. Another example, more suiting to the name, is of the Earth slowing its rotation via the seas and oceans gravitional pull on the moon. A planet (from the Greek πλανήτης, planētēs or wanderers) is a body of considerable mass that orbits a star and that produces no energy through nuclear fusion. ...

Pierre-Simon Laplace - Wikipedia, the free encyclopedia (3088 words)
The subject is one of great difficulty, and though it seems certain that the solar system has a common origin, there are various features which appear almost inexplicable on the nebular hypothesis as enunciated by Laplace.
Probably the best modern opinion inclines to the view that nebular condensation, meteoric condensation, tidal friction, and possibly other causes as yet unsuggested, have all played their part in the evolution of the system.
The idea of the nebular hypothesis had been outlined by Kant in 1755, and he had also suggested meteoric aggregations and tidal friction as causes affecting the formation of the solar system: it is probable that Laplace was not aware of this.
The Earth-Moon System (3264 words)
The scientist who wrote the Encyclopedia Britannica article on tidal friction wrote that, “The mutual attraction between the Moon and the material in the [tidal] bulge tends to accelerate the Moon in its orbit…” To accelerate in this case means to increase the velocity.
In addition, the tidal bulge in the past would have been much larger than at present since the moon was much closer.
The point to this argument is that the fast rotation of the early Earth weakens the tidal acceleration of the Moon, whereas most creationist arguments assume the opposite, that it would strengthen tidal acceleration.
