The other case of a moving frame of reference studied here is: . ... That is a force towards the center of rotation, of magnitude F centripetal = mV 2 / R where R is the radius of the circle of rotation and V is the velocity of motion around it. ...

... 22.Reference Frames . ... Inertial Forces . 23a. The Centrifugal Force . ... When calculating the motions of the oceans and the atmosphere, it is much easier to use reference points on the rotating Earth and add a centrifugal force to all equations. ... The rest arises because the Earth is not a perfect sphere: the centrifugal force of its rotation causes its equator to bulge out , making the surface there more distant from the Earth s center and thus weakening the gravitational pull. ...

The automatic flag raising system on a horizontal flagpole attached to the vertical outside wall of a tall building has become stuck. ... One side of the flagpole is attached to the wall of the building by a hinge so that it can rotate vertically. 3 m away, the other end of the flagpole is attached to a strong, lightweight cable. The cable goes up from the flagpole at an angle of 30 until it reaches the building where it is bolted to the wall. ...

EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

... In this paper, we present an interactive signal-processing environment called Grid. ... Grid is a graphical interactive multi-threaded signal-processing environment which allows the creation of complex arrays of algorithms (called units within Grid) by simply choosing the desired units from a selection of toolboxes then graphically wiring them together. Figure: Grid's ToolBox window consists of a section which lists the available toolboxes and another showing its associated tools. ...

... But the Moon has another influence on the Earth that cause changes noticeable only over longer periods of time. ... This wouldn't matter if the Moon orbit was aligned with the Earth's equator. ... The Earth's spin resists this change. The tug-of-war between spin and Moon causes the Earth's axis to precess , or wobble. ... The spring equinox occurs when the path of the Sun on the sky crosses the Earth's equatorial plane moving north. ... What are the reasons for the Earth's seasons? ...

The solar system probably formed about 4.5 billion years ago from a giant disk of gas, dust and ice in space. ... All forms of life on Earth require liquid water to survive, so the presence of liquid water is a good criterion for deciding whether other planets in the universe could be habitable. Earth is the only habitable planet in the solar system. Venus, closer to the Sun, is too hot to have liquid water. Planets and moons in the outer solar system are too cold for liquid water. ...

Most commonly, binoculars utilize either porro prisms or roof prism s for this purpose. ... Example: The Meade 8x42mm Waterproof roof prism binocular has a field of view 367 ft. wide for an object 1000 yards distant from the observer, yielding a field of view specification of 367 ft. at 1000 yds. ...

... This applet generates an observing list based on an observer's location and time. ... To use this program, enter in your location, and the local times at which you wish to begin and end observing. The date you enter should correspond to the calendar day at the time at which you begin observing. For example, if you wish to observe from 9:37 PM October 23, 2007 until 3:21 AM October 24, 2007, you would enter 21:37 for the starting time, 03:21 for the finish time, and 10/23/2007 for the date. ...

... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...
