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.
The force of Gravity is  determined by the mass and distance between two or more objects.  The other force that keeps the moon in o â¦ rbit is the moon's inertia.  Without inertia the moon would simply fall into Earth; because of  Gravity, the same would happen with the planets and the sun.Answered.hat's the mutual force of gravitation (gravity) between the Earth and the Moon. This, combined with the Moon's velocity (its inertia), results in the orbital path that the â¦ Moon follows. 50 people found this useful. Al Cohen.
