What is the the force of gravity on each planet?

Answer 1

Mercury - 3.7 m/s 2 (0.38 g)

Venus - 8.87 m/s 2 (0.904 g)

Earth - 9.780327 m/s 2 (0.99732 g)

Mars - 3.711 m/s² (0.376 g)

Jupiter - 24.79 m/s 2 (2.528 g)

Saturn - 10.44 m/s² (1.065 g)

Uranus - 8.69 m/s 2 (0.886 g)

Neptune - 11.15 m/s 2 (1.14 g)

Answer 2

In terms of g, where 1 g is the acceleration due to gravity on earth, the other planets have the following values for g;

Answer 3

It's best to talk about force per kilogram, because the force increases with the mass that is being attracted. So the scientific units are "Newtons per kilogram".

Also you need to say where you are measuring the force because it depends on distance. It is usual to talk about the force at the planet's surface.

Now for the answer:

Mercury : 3.71

Venus : 8.90

Earth : 9.81

Mars : 3.70

Jupiter : 26

Saturn :11

Uranus : 9

Neptune : 12

I have only given approximate values for the giant planets because there are

disagreements about these numbers amongst scientists.
