"Newton's Law"




1st Law:   Defines the Law of Force:
           A body remains at rest or moves with constant velocity in a straight
           line unless acted upon by a force.

2nd. Law:  Defines Mass:
           The amount of force necessary to accelerate a body depends on the mass 
           of the body.

           If the same force is applied to two bodies of different masses it will 
           produce a greater acceleration in the smaller body than in the larger body.

3rd. Law:  The action of a force always produces a reaction in the body.
           The reaction is of equal magnitude but opposite in the direction of the action.


"Newton's Law of Gravitation"




1.  The force by which a body attracts another body increases with the mass of the object it
    attracts.


2.  The bigger the object, the stronger the call of gravity.


3.  If a object is small, its inertia or tendency to resist motion is small, but the force that
    gravity exerts upon it is also small.


4.  If a object is big, its inertia is great, the force that gravity exerts upon it is also great.


5.  Gravity is always exerted in the precise degree necessary to overcome the inertia of any object,
    therefore, that is why all objects fall at the same rate regardless of their inertial mass.


"The Principle of Equivalence of Gravitation & Inertia"




1.  There is no way to distinguish the motion produced by inertial forces (Accereration, Recoil, 
    Centrifugal Force, etc) frpm motion produced by gravitational force.


2.  This is evident when flying an airplane. In an airplane it is impossible to seperate the effects
    of inertia from those of gravitation. 


3.  The physical sensation of pulling out of a dive is exactly the same as that produced by exacuting
    a steeply banked turn at high speed.


4.  In both cases the factor known to flyers as a "G-Load", (Gravity Load) appears. Blood is drawn from
    away from the head, and the body is pulled heavily down into the seat. To the pilot who is
    flying "blind" and without instruments, these effects can be fatal.
