Editing Coriolis force (section)

==Intuitive explanation==
For an intuitive explanation of the origin of the Coriolis force, consider an object, constrained to follow the Earth's surface and moving northward in the Northern Hemisphere. Viewed from outer space, the object does not appear to go due north, but has an eastward motion (it rotates around toward the right along with the surface of the Earth). The further north it travels, the smaller the "radius of its parallel (latitude)" (the minimum distance from the surface point to the axis of rotation, which is in a plane orthogonal to the axis), and so the slower the eastward motion of its surface. As the object moves north it has a tendency to maintain the eastward speed it started with (rather than slowing down to match the reduced eastward speed of local objects on the Earth's surface), so it veers east (i.e. to the right of its initial motion).<ref>{{cite book |title=Solar Energy at Urban Scale |first1=Benoit |last1=Beckers |publisher=John Wiley & Sons |year=2013 |isbn=978-1-118-61436-5 |page=116 |url=https://books.google.com/books?id=GAOnjP4k7SQC}} [https://books.google.com/books?id=GAOnjP4k7SQC&pg=PT116 Extract of page 116]</ref><ref>{{cite book |title=Energy and the Environment: Resources, Technologies, and Impacts |first1=Reza |last1=Toossi |publisher=Verve Publishers |year=2009 |isbn=978-1-4276-1867-2 |page=48 |url=https://books.google.com/books?id=-cb2EyrWbg0C}} [https://books.google.com/books?id=-cb2EyrWbg0C&pg=PA48 Extract of page 48]</ref>

Though not obvious from this example, which considers northward motion, the horizontal deflection occurs equally for objects moving eastward or westward (or in any other direction).<ref>{{Cite web|url=https://ocw.mit.edu/courses/earth-atmospheric-and-planetary-sciences/12-090-introduction-to-fluid-motions-sediment-transport-and-current-generated-sedimentary-structures-fall-2006/course-textbook/ch7.pdf |archive-url=https://web.archive.org/web/20150907214831/http://ocw.mit.edu/courses/earth-atmospheric-and-planetary-sciences/12-090-introduction-to-fluid-motions-sediment-transport-and-current-generated-sedimentary-structures-fall-2006/course-textbook/ch7.pdf |archive-date=2015-09-07 |url-status=live|title=MIT: Flow in rotating environments}}</ref> However, the theory that the effect determines the rotation of draining water in a household bathtub, sink or toilet has been repeatedly disproven by modern-day scientists; the force is negligibly small compared to the many other influences on the rotation.<ref>{{cite journal |doi=10.1119/1.4897580 |title=Debunking Coriolis Force Myths |journal=The Physics Teacher |volume=52 |issue=8 |pages=464–465 |year=2014 |last1=Shakur |first1=Asif |bibcode=2014PhTea..52..464S}}</ref><ref name = SciAmer2/><ref>{{Cite web|url=https://www.snopes.com/fact-check/coriolis-effect/|title=Coriolis Force Effect on Drains|website=Snopes.com|date=28 April 2003 }}</ref>
