On the Terms “Centrifugal Force” and “Force of Inertia”

Centrifugal force in Kerr geometry

We have obtained the correct expression for the centrifugal force acting on a particle at the equatorial circumference of a rotating body in the locally non-rotating frame of the Kerr geometry. Using this expression for the equilibrium of an element on the surface of a slowly rotating Maclaurin spheroid, we obtain the expression for the ellipticity (as discussed earlier by Abramowicz and Miller...

the effect of task complexity on efl learners’ written task performance in terms of accuracy and complexity

هدف اصلی این تحقیق بررسی تاثیر افزایش میزان پیچیدگی تکالیف مکالمه محور بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 15 الی 18 سال درسطح pre-intermediate از طریق petو vhs تست به عنوان شرکت کنندگان در تحقیق انتخاب شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی دو تکلیف ساده و پیچیده را طی 2 جلسه انجام...

Some Observations on the Effect of Centrifugal Force in Man.

ANY flight manoeuvre, whether simple or complex, imposes varying degrees or types of acceleration upon the aircraft and the crew. Centripetal acceleration is developed when an aircraft is moving in a curved path, and its value is directly proportional to the square of the angular velocity. For a constant indicated air-speed, the centripetal acceleration is inversely proportional to the radius o...

Biased rankings: The centrifugal and centripetal force of randomness

We study the ranking of entities, in terms of a metric which is averaged across the entities’ constituting units, such as countries (entities) being ranked in terms of the average height (metric) of their inhabitants (units). We show that when 1) the entities differ in terms of the number of units they contain (e.g. countries with different numbers of inhabitants), and when 2) part of the varia...
