The image above represents gravitational acceleration.

To compute for gravitational acceleration, three essential parameters are needed and these parameters are **Gravitational Constant (G), Mass of the Earth (m _{E}) **and

**Radius of the Earth (R).**

The formula for calculating gravitational acceleration:

a = ^{GmE} / _{R²}

Where:

a = Gravitational Acceleration

G = Gravitational Constant

m_{E} = Mass of the Earth

R = Radius of the Earth

Let’s solve an example;

Find the Gravitational acceleration when the gravitational constant is 6.67E-11, the mass of the earth is 12 and the radius of the earth is 21.

This implies that;

G = Gravitational Constant = 6.67E-11

m_{E} = Mass of the Earth = 12

R = Radius of the Earth = 21

a = ^{GmE} / _{R²}

a = ^{(6.67e-11)(12)} / _{(21)²}

a = ^{8.004e-10} / _{441}

a = 1.81e-12

Therefore, the **gravitational acceleration **is **1.81e-12 m/s.**
