Question

what is an acceleration ? Name the S.I.unit?​

Answer 1

Explanation:

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.

Hope this helps:)

Answer 2

Explanation:

acceleration is a vector quantity that is defined as the rate at which an object change its velocity. an object is accelerating if it is changing its velocity

the SI unit of acceleration is metre per second square or

m/s².
