In this lecture briefly analyzing the Acceleration Vector. An object’s acceleration canbe decomposed into components parallel and perpendicular to the velocity. An object changing direction always has a component of acceleration perpendicular to the direction of motion. Since acceleration is a velocity change over a time, the units on acceleration are velocity units divided by time units – thus (m/s)/s or (mi/hr)/s. The (m/s)/s unit can be mathematically simplified to m/s².
