Question

Why does (second)^2 occurs in acceleration?

Answer 1

Answer:

Unit of displacement is unit of length, i.e. m. Unit of acceleration is unit of (velocity/time), i.e. (m/s)/s = m/s2. so SI unit of velocity is m/s and SI unit of time is second. so when we divide (m/s)/s=so we get m/s square.

Answer 2

Answer:if you consider vilocity vs time graph then acceleration will be area under curve, unit of vilocity is m/s hence area i.e acceleration will become m/s^2
