Compare the gravitational force on a 4 kg mass at the surface of the Earth (with radius 6.4 × 106 m and mass 6 × 1024 kg) with
that on the surface of the Moon
with mass
1
81.3
ME and radius 0.27 RE

.

What is the force on the Moon?
Answer in units of N.

Please note that the ration between the gravitation force 435 and the mass 44.5

The mass of the Moon is M / 81.3.

The radius of the Moon is R × 0.27.

The gravitational force on the moon would be

G(M/81.3)m/(R×0.27)² = 0.17×GMm/R²

The gravitational force on the moon is smaller by the factor of about 0.17.

the results is a decrease in air temperature with an increase of altitude.
