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.
When an unbalanced force is applied to an object, the object will accelerate. The size of the acceleration depends upon the force applied and the mass of the object. There is a relationship between force, mass and acceleration (force = mass Ã acceleration). Gravity is a force that attracts objects with mass towards each other. The weight of an object is the force on it due to gravity. There is a relationship between weight, mass and acceleration of free-fall (weight = mass Ã acceleration of free-fall). The gravitational field strength of the Earth is 10 N/kg and its acceleration of free-fall is 10 m/s 2.
