The SI unit of acceleration is _________.
meters per seconds squared
Acceleration is the rate of change of velocity: \(a = \dfrac{\Delta v}{\Delta t}\). Velocity has SI unit m/s and time has SI unit s, so the SI unit of acceleration is \(\dfrac{\text{m/s}}{\text{s}} = \text{m/s}^2\) — metres per second squared.
m/s is the unit of velocity; s/m and s/m² are not units of any standard kinematic quantity.
