**drwls**, Thursday, June 23, 2011 at 6:24pmThe value of the acceleration of gravity "g" on Mars is

G*M/R^2

where the M and R are the mass and radius of Mars, which you have provided.

G is Newton's universal gravity constant.

Compare the Mars g to the g value on Earth, which is 9.8 m/s^2.

g is less on Mars. Weights on Mars will be reduced by the same factor.

**Damon**, Thursday, June 23, 2011 at 6:28pmYOU MEAN:

6.042e23 kg and a radius of 3.038e6

Kg, mass, is the same everywhere.

weight in Newtons is m * local g

Fearth = m g = 9.81*60 = 588.6 Newtons = weight on earth

on Mars:

F = G 60 Mmars/Rmars^2

= 6.67*10^-11 * 60 * 6.042*10^23/(3.038^2*10^12)

= 262*10^0 = 262 N = weight on Mars
