Definition:Average Acceleration

Definition
Let $B$ be a body in motion.

Let $\Bbb I = \closedint {t_1} {t_2}$ be a time interval.

Let $\mathbf v_1$ and $\mathbf v_2$ be the velocity of $B$ at $t_1$ and $t_2$ respectively.

The average acceleration of $B$ during $\Bbb I$ is defined as the change of velocity during $\Bbb I$ divided by the length of $\Bbb I$:


 * $\overline {\mathbf a} := \dfrac {\mathbf v_2 - \mathbf v_1} {t_2 - t_2}$
