What is the acceleration due to gravity on (a) Venus, (b) Pluto, and (c) the moon?
Acceleration due to gravity on the surfce of a Very large Body can be calculated using the following formula:
Where G= Universal Gravitational Constant (6.673×10−11N-m2Kg2)
M= Mass of Very large body
r= Radius of Very large body
Note: This formula is derived with the help of Newton's Second law (F= m.a) and Equation of Gravitational Force.
A). Acceleration due to gravity on Venus (gvenus) = G.Mvenus/ rvenus2
Mvenus=4.867 × 1024 kg
rvenus= 60518 x 102 m
gvenus = (6.673×10−11N-m2Kg2) (4.867 × 1024 kg) / (60518 x 102 m)2
gvenus = 8.82 m/s2
B). Acceleration due to gravity on Venus (gPluto) = G.Mpluto/ rpluto2
Mpluto= 1.31 × 1022 kg
rpluto= 11883 x 102 m
gPluto= (6.673×10−11N-m2Kg2) (1.31 × 1022 kg) / (11883 x 102 m)2
gPluto= 0.62 m/s2
A). Acceleration due to gravity on Venus (gmoon) = G.Mmoon/ rmoon2
Mmoon= 7.35 × 1022 kg
rmoon= 17371 x 102 m
gmoon= (6.673×10−11N-m2Kg2) (7.35 × 1022 kg) / (17371 x 102 m)2
gmoon = 1.625 m/s2
