If we choose as the unit of

of time to the velocity of a point , an

velocity in unit of time -- and , therefore , at units of velocity in t units of time .

If we choose as the unit of

**acceleration**that which adds a unit of velocity per unitof time to the velocity of a point , an

**acceleration**measured by a will add a units ofvelocity in unit of time -- and , therefore , at units of velocity in t units of time .
