Calculating acceleration involves dividing velocity by time — or in terms of units, dividing meters per

**second**[m/s] by**second**[s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the**meter**per**second**squared.Also asked, what is the SI base unit for acceleration?

Derived quantity | Name | Symbol |
---|---|---|

speed, velocity | meter per second | m/s |

acceleration | meter per second squared | m/s^{2} |

wave number | reciprocal meter | m^{-}^{1} |

mass density | kilogram per cubic meter | kg/m^{3} |

How can you use the definition of acceleration to explain the units in which acceleration is measured?

In physics or physical science,

**acceleration**(symbol: a) is**defined**as the rate of change (or derivative with respect to time) of velocity. It is thus a vector quantity with dimension length/time². In SI**units**,**acceleration is measured**in meters/second²**using**an accelerometer.
