1. There is apparently no relationship between gravity and a vacuum. A vacuum is any space where there is no matter i.e empty space. Gravity acts on matter. 2. Pressure is the force exerted on a unit area. Atmospheric pressure is the force or weight which the air/atmosphere exerts on a particular object, gravity itself is the earth's natural force. Therefore the force per unit area exerted by the atmosphere is a function of gravity and the mass of the air column, without gravity there could be no atmospheric pressure. 1 Like |
