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/timeÂ². In SI units, acceleration is measured in meters/secondÂ² using an accelerometer. To accelerate an object is to change its velocity, which is accomplished by altering either its speed or direction (like in case of uniform circular motion) in relation to time. In this strict mathematical sense, acceleration can have positive and negative vals (deceleration).
