yes
because some countries are higher than others
Yes, all countries have rights. Some have less than others.
The moon has less mass than does Mars and therefore has less gravity at its surface.
Yes, it is significantly less.
The moon has less mass than Earth. Gravity is proportional to mass, so there is less gravity on the moon.
Why does Mercury and Mars have less gravity than Earth because they both have less mass than does the Earth.
Some countries have better health care, and less murders.
Gravity is the attraction between masses. And since the moon has less mass than earth, the gravity is weaker there. Over a distance gravity is weaker.
No it's all based on the mass of the Earth so it's the same.
There is much less gravity on Mercury.
less
It doesn't. The moon has less gravity than Earth because it has less mass.
