The approximate acceleration of gravity for an object above the earth's surface is 9.8 m/s².
<h3>Acceleration due to gravity </h3>
The acceleration due to gravity of an object above the Earth's surface is calculated from Newton's second law of motion and Newton's law of universal gravitation.
<h3>Force between the object and Earth</h3>Solve (1) and (2)
mg = GmM/R²
g = GM/R²
where;
- M is mass of Earth
- G is gravitational constant
- R is radius of the Earth = 6,371 km
g = (6.673 x 10⁻¹¹ x 5.98 x 10²⁴)/(6,371 x 10³)²
g = 9.8 m/s²
