9.8 M S2 To Newtons

SI derived unit of measurement of acceleration

Metre per second squared
Unit system	SI
Unit of	acceleration
Symbol	m / sii

The metre per 2nd squared is the unit of acceleration in the International System of Units (SI). Equally a derived unit of measurement, it is composed from the SI base units of length, the metre, and fourth dimension, the 2d. Its symbol is written in several forms as g/sⁱⁱ , m·due south⁻² or ms⁻² , ${\displaystyle {\tfrac {\operatorname {m} }{\operatorname {due south} ^{ii}}}}$ , or less commonly, as m/due south/south.^[1]

As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.east. metre per 2nd per second and is treated as a vector quantity.

Instance [edit]

An object experiences a abiding acceleration of one metre per second squared (1 grand/s^two) from a country of residual, then information technology achieves the speed of 5 one thousand/southward after 5 seconds and 10 thousand/southward after 10 seconds. The average dispatch a can be calculated by dividing the speed v (m/s) by the fourth dimension t (s), and then the average acceleration in the kickoff instance would exist calculated: ${\displaystyle a={\frac {\Delta v}{\Delta t}}={\frac {5{\text{ chiliad/s}}}{5{\text{ s}}}}=1{\text{ (m/s)/s}}=1{\text{ m/south}}^{two}}$ .

[edit]

Newton'south second constabulary states that force equals mass multiplied past dispatch. The unit of force is the newton (Northward), and mass has the SI unit kilogram (kg). One newton equals one kilogram metre per 2nd squared. Therefore, the unit metre per 2nd squared is equivalent to newton per kilogram, N·kg⁻¹, or N/kg.^[ii]

Thus, the Earth's gravitational field (almost ground level) tin be quoted as 9.8 metres per 2d squared, or the equivalent 9.8 N/kg.

Acceleration tin can be measured in ratios to gravity, such every bit one thousand-force, and summit ground acceleration in earthquakes.

Unicode grapheme [edit]

The "metre per second squared" symbol is encoded past Unicode at code point U+33A8 ㎨ Foursquare 1000 OVER Due south SQUARED. This is for compatibility with E Asian encodings and not intended to be used in new documents.^[3]
