Despite the fact that man has not changed one iota physiologically, the technological advancements that have occurred in the last fifty years would normally have taken at least two hundred years to make. There's a reason. We had help. That help came from technology found in downed alien spacecraft.
many other objects.The strength of the gravitational force between two objects depends on two factors,mass and distance. The Mass of the Objects The more mass two objects have,the greater the force of gravity the masses exert on each other.If one of the masses is doubled,the force of gravity between the objects is doubled.
1 Weight: force due to gravity -9.81m/sÂ². 2  Force: a pushing or pulling action that causes a change of state (rest/motion) of a body is proportional to mass x acceleration. 3  It is measured in Newtons (N) where 1N is the force that will produce an acceleration of 1 m/sÂ² in a body of 1kg mass.
