Question

As we move at higher altitude, the value of $g$_____ .

Answer 1

Acceleration due to gravity:

1. The acceleration of a body due to the gravitational force of attraction is called acceleration due to gravity $\left(g\right)$.

2. When the height increases beyond a certain on the surface of the Earth, the equation for acceleration due to gravity is given by : $g_h=g{\left[\frac{R}{R+h}\right]}^2$

$g_h$⇢ Acceleration due to gravity at a height $h$

$g$⇢ Acceleration due to gravity near the surface of the Earth

$R$⇢ Radius of the Earth

$h$⇢Height from the surface

3. From the above equation, $g$is inversely proportional to height $h$. Thus, if the height from the surface of the Earth increases then $g$ decreases.

Hence, we can say that as we move at higher altitudes, the value of $g$ decreases.
