Question

because acceleration is the change in velocity over time ($a = \frac{delta v}{t}$) the units are

Explanation:

Step1: Recall velocity and time units

Velocity has units of $\frac{m}{s}$, time has units of $s$.

Step2: Calculate acceleration units

Acceleration $a=\frac{\Delta v}{t}$, so units are $\frac{\frac{m}{s}}{s}=\frac{m}{s^{2}}$.

Answer:

$\frac{m}{s^{2}}$
