Know that the acceleration due to gravity is not a universal constant but depends on location in the universe. Know that on earth, the acceleration due to gravity is often modelled to be a constant, $g~m~s^{-2}$.

$g ≈ 10$, $g ≈ 9.8$

Unless otherwise specified, in examinations the value of $g$ should be taken to be $9.8$.

Notation:

• Acceleration due to gravity, $g~m~s^{-2}$.

Excludes: Inverse square law for gravitation.
