What vehicle can overcome earth's gravity because it expels a gas with a force equal to the pull of gravity?

That sounds like a "hovercraft", which doesn't rise or fall, but just exactly hangs there.
If the vehicle expels a gas with a force GREATER than the pull of gravity ... like a rocket for example ...
then it can actually rise.

Moon gravity vs earths gravity?
Moon gravity is less because the atmosphere and mass and the earths gravity is greater than the moon if you weight yourself in the earth and then you weighted yourself in the moon you would weight less in the moon you could actually float in the moon because of its atmosphere and mass
