The escape velocity of the moon is less than the average velocity of the atom or molecule of gases. Hence all gas molecules escape out of moon's gravitational field .
Which is always constant for a machine of given design: MA or VR ? Ans: VR remains constant for a machine of given design as it depends on the distances moved by the load and effort but MA can vary due to the friction developed between the moving parts of the machine.
