Gravitational Acceleration:
Gravitational Acceleration is the acceleration of an object caused by the
force of gravity from another object.
Gravitational Acceleration:
Gravitational Acceleration: 
Planet Mass: 
Radius from Planet Center: 
where,
G = Universal Gravitational Constant = 6.6726 x 10-11N-m2/kg2
M = Planet Mass
r = Radius from Planet Center
Gravitational Acceleration Examples:
Case 1: What is the acceleration due to gravity on Earth?
Mass of the earth = 5.98x1024 kg, Radius of the earth = 6378100 m,
G = 6.6726 x 10-11N-m2/kg2.
Step 1: Substitute the values in the below Gravitational Acceleration formula:
This example will guide you to calculate the Gravitational Acceleration manually.
Case 2: Determine the Moon's radius? The gravitational acceleration of the moon is 1.63 m/s2
Mass of moon = 7.36 x 1022 kg, a = 1.63 m/s2,
G = 6.6726 x 10-11N-m2/kg2.
Step 1: Substitute the values in the below Radius formula:
This example will guide you to calculate the Radius of the Moon manually.
