Question

Identify which of the following best define the average acceleration:

• A. dividing the change in velocity by the change in time.
• B. dividing the change in time by the change in velocity.
• C. multiplying the change in velocity by the change in time.
• D. multiplying time by velocity.
• E. dividing the velocity by the time.

Answer 1

The correct option is A dividing the change in velocity by the change in time.

The average acceleration of a body with velocities $v_1$ and $v_2$ at times $t_1$ and $t_2$ is given by $a_{avg}=\frac{v_2-v_1}{t_2-t_1}$

$=\frac{\Delta v}{\Delta t}$.
