Question

Why is acceleration measured in meters / seconds squared?

Answer 1

Acceleration is the rate of velocity. Velocity is rate of distance travelled. Therefore

Velocity= Distance/Time

(Since unit of distance is metre and time is second)

Velocity= m/s

Acceleration= Velocity/time

(Velocity= m/s and time is second)

Acceleration= m/s/s

Acceleration=

$\frac{m}{s} \times \frac{1}{s}$

Therefore, Acceleration=

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