Question

Define acceleration and write its S.I unit.

Answer 1

1. Acceleration may be defined as the rate of change of velocity with respect to time.
2. Mathematically we can define acceleration as, $\mathrm{Acceletaion}\left(\mathrm{a}\right)=\frac{\mathrm{Velocity}\left(\mathrm{v}\right)}{\mathrm{Time}\left(\mathrm{t}\right)}$.
3. The S.I unit of acceleration is $m/s^2.$
