time dilation b/c of Gravitaional field strength

Can gravitational field strength cause time dilation.
as G.F.S on earth is 10 N/kg and on moon it is 1.6 N/kg. so will a clock on the moon surface tick slowly for the observer on earth or not?

Actually from what i remember it should be the other way around i.e. the chap on the moon will see the earth clock run slower as the "grav" field is greater on earth.

But artificial gravity is provided in gravity free space satellite to increase the efficiency of the persons inside.
It means they moves very slow in G. free space, and clock too?
Does vibration of cesium atom also change?

When compared to time measured locally elsewhere then the answer is yes. It's known under various names such as gravitational time dilation and gravitational redshift. The stronger the difference between the fields the greater the strength of the time dilation. Note: It's quite possible to have time dialtion in the absense of spacetime curvature.

The gravitational field at the surface of the earth is stonger than that measured at the surface of the moon. Therefore clocks at the surface of each the earh and moon will have the earth's clock running slower than that moon's.
