# Acceleration

Acceleration, abbreviated as a, is the rate of change of velocity with time. Like velocity, this is a vector quantity that has a direction as well as a magnitude. Whenever a mass experiences a force, an acceleration is acting. An increase in velocity is commonly called acceleration while a decrease in velocity is deceleration. Acceleration is a vector quantity having magnitude and direction, some of these include displacement, drag, force, lift, momentum, thrust, torque, velocity and weight.

\(\large{ a }\) = acceleration | \(\large{\frac{ft}{sec^2}}\) | \(\large{\frac{m}{s^2}}\) |

\(\large{ t }\) = time | \(\large{sec}\) | \(\large{s}\) |

\(\large{ \Delta v }\) = velocity differential | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |

\(\large{ v_i }\) = initial velocity | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |

\(\large{ v_f }\) = final velocity | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
