Because gravity depends not only on the mass, the volume, the density and the speed of rotation of the planet but also on local specificities such as presence of water, of mountains etc.
The earth's mantle is not homogeneous so the effects of gravity differs from a region to another.
is 20x earths
No the Earth would pull u more than the moon
Yes, that's basically what causes tides. ===================== And the moon. Lets not forget its role.
its is different ok :)
The Earth and the object exert a gravitational force on each other, but only the Earth's is big enough to measure. So, the formula for gravitational force include the distance from one body's surface to its center and the same for the other body. The length of the radius is directly proportional to the body's gravitational force.
yes
9.8 N/kg
it was invented by the earths gravitational feild
is 20x earths

The moon is small.

Yes.
Commonly referred to as the object's "weight".Note: The object also exerts the same identical gravitational force on the earth.Earth
yes because it helps our earth to take movement
its is different ok :)
mass varies directly with gravitational force. Gravitational force is just another way of saying weight, which is represented by the equation, F=W=mg ; where F is force of gravity, W is weight, m is mass, and g is acceleration due to earths gravity (roughly 9.8 m/s2)
