The standard acceleration of gravity or standard acceleration of free fall, often called simply standard gravity and denoted by ɡ 0 or ɡ n, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth.
It does not include the reduction of constraint force that we perceive as a reduction of gravity due to the rotation of Earth, and some of gravity being counteracted by centrifugal force. There are significant uncertainties in the values of r and m 1 as used in this calculation, and the value of G is also rather difficult to measure precisely.
While New Zealand is majority English-speaking, its two official languages are Māori [111] and New Zealand Sign Language. [112] The United Kingdom does not have an official language. In Wales and Northern Ireland, English is co-official alongside Welsh [113] and Irish [114] respectively. Neither Scotland nor England have an official language.
Spanish-speaking countries [ edit ] In many Spanish-speaking countries (and the Philippines), " Día de los Santos Inocentes " ( Holy Innocents Day ) is a festivity that is very similar to April Fools' Day, but is celebrated in late December (27, 28 or 29 depending on the location).
The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
Mexico, [a] [b] officially the United Mexican States, [c] is a country in the southern portion of North America.Covering 1,972,550 km 2 (761,610 sq mi), [12] it is the world's 13th largest country by area; with a population of over 130 million, it is the 10th most populous country and has the most Spanish speakers in the world.

In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.
According to the 2020 Mexican government census, 78% of the population has a Roman Catholic background, while 10% come from a Protestant or evangelical Protestant background. [1] In 2010 those who declared themselves Catholics represented 83.9% of the population aged 5 and older, evangelical Protestants 7.6%, other religions 2.5% and 4.6% ...
