==Description==

In [[physics]], and more specifically [[kinematics]], '''acceleration''' is the [[change]] in [[velocity]]  over time. Because velocity is a [[vector]], it can [[change]] in two ways: a change in [[magnitude]] and/or a change in direction. In one [[dimension]], i.e. a line, acceleration is the [[rate]] at which something [[speed]]s up. However, as a vector [[quantity]], acceleration is also the rate at which direction changes. Acceleration has the dimensions L T  −2. In SI units, acceleration is [[measured]] in meters per second squared (m/s2).
