When comparing mass and size data for the planets Earth and Mars, it is observed that Mars 2 points is 10 times less massive than Earth. Theoretically speaking this means that objects on
Mars should have a weight of 10% they are on Earth. For example, a chemistry teacher who
weighs 700 N on Earth should weigh 70 N on Mars, but this is not the case. A 700 N person
on Earth actually weighs about 265 N on a surface of Mars. Considering the circumstance
and using two known constants 9 = 9.8 m/s 2 and G = 6.67x10^(-11) Nm 2/kg 2. Is
there a difference between the mass of an object on Earth and its mass on Mars? Why should
the chemistry teacher's weight on Mars be almost 4 times expected in the original claim?
