Symbol	chiliad / southward²

The metre per second squared is the unit of measurement of acceleration in the International System of Units (SI). As a derived unit, information technology is equanimous from the SI base units of length, the metre, and fourth dimension, the second. Its symbol is written in several forms every bit k/sⁱⁱ , m·s⁻² or ms⁻ⁱⁱ , ${\tfrac {\operatorname {m} }{\operatorname {s} ^{2}}}$ , or less commonly, as m/s/s.^[1]

As acceleration, the unit is interpreted physically every bit change in velocity or speed per time interval, i.e. metre per second per second and is treated every bit a vector quantity.

Example [edit]

An object experiences a constant dispatch of ane metre per second squared (1 1000/south²) from a state of remainder, then it achieves the speed of 5 k/s after 5 seconds and 10 thou/s after 10 seconds. The boilerplate dispatch a can exist calculated by dividing the speed five (m/due south) past the time t (s), so the average acceleration in the first example would exist calculated: $a={\frac {\Delta v}{\Delta t}}={\frac {5{\text{ m/due south}}}{v{\text{ s}}}}=one{\text{ (m/s)/south}}=one{\text{ m/s}}^{2}$ .

[edit]

Newton'southward second police states that force equals mass multiplied by acceleration. The unit of force is the newton (N), and mass has the SI unit kilogram (kg). One newton equals one kilogram metre per second squared. Therefore, the unit of measurement metre per second squared is equivalent to newton per kilogram, N·kg⁻¹, or N/kg.^[2]

Thus, the Earth's gravitational field (near ground level) can be quoted as ix.viii metres per second squared, or the equivalent nine.viii N/kg.

Acceleration can be measured in ratios to gravity, such equally g-force, and peak ground acceleration in earthquakes.
