Question

The average value of acceleration due to gravity at sea level is ___ $m{s}^{-2}$.

Answer 1

Gravity:

1. The direction of the acceleration due to gravity is always downwards.
2. The magnitude of gravity is approximately $9.8m{s}^{-2}$ on the earth's surface.

Hence, the average value of acceleration due to gravity at sea level is $\mathbf{9}\mathbf{.}\mathbf{8}\mathbf{}\mathit{m}{\mathit{s}}^{\mathbf{-}\mathbf{2}}$.
