The mechanism of falling object is always an interested topic. Almost all physicists think that gravitational force acts on object and makes it have weight and free fall. Here a very simple experiment negates the above parlance.
Galileo demonstrates that different mass bodies increased their speed at the same rate (Stephen [1]). Galileo phenomenon implies that there may be two different mechanisms that govern it. One is the equality of gravitational and inertial mass based on facts that object has weight (Einstein [2]). Another is that falling object is not governed by gravity. Under this condition, falling object must be weightless and stay on how it is left in falling process. So, falling object is passive.
Let us see a very simple experiment.
A object, a solid iron ball (diameter is 4cm) with a long handle (diameter 0.5 cm and length 15 cm), is kept on balance by hand at angle 0,60,90,120 degrees with vertical line respectively in air showed in Fig. up-up A, B, C, D. Release the object, and then it is free falling. The angles of object in space are always not changing in free falling process showed in Fig up-down A, B, C and D. The object stays on how it is left. Its solid ball with big mass does not go further downwards than handle with less mass. When the process of free falling object is blocked by floor, it falls down on it at once because of weight showed in Fig up-down E.
Obviously, the object is weightless. Its weight does not exhibit, until it meets resistance. If it has weight in free falling process, the ball part with very big mass is very heavy and must be more downwards than light handle.
Weightlessness, unchangeable state and Galileo phenomenon are three properties of free falling object. Weightlessness verifies that Galileo phenomenon is not a direct consequence of the equality of gravitational and inertial mass.
Time-space or field of anybody is spherical. Its curvature direction points to center. The curvature direction of time-space of two bodies is always opposite. This is the reason why they attract each other. In their closing process, they respectively move from other’s low curvature to high. In a word, the motion of them is the direct consequence of time-space curvature contraction. Gravity is not the cause of attraction between two bodies. Any force including gravity is an index of resistance (Zhai [3]).
The time-space of the Earth is very big, but that of an iron boll employed in experiment limited. So, the Earth can be seen as a fixed body, the phenomenon of falling object is just the result of its time-space converging at center.
In this way, the curvature surface of time-space of the Earth on which object stays converges at its center. Object that follows the motion of time-space curvature surface falls showed in Fig 2. The motion of falling object is passive one. This is reason why object in falling process is weightless and continue in rest or motion. So, it is easy to understand why the acceleration of falling object does not concern with mass.
When object meets resistance, it gets behind the curvature surface motion of time-space that moves continually. So, weight that resists the change in height may be seen as an index of mass inertia, not gravitational force, because the change in quantities of mass only causes the change in weight, not in gravitational acceleration determined by curvature and curvature intensity of time-space (Zhai [3]). The change in weight is equal to that in inertia. This is reason why inertial and gravitational mass is equality and exactly proportional to one another. Weight is a direct consequence of passive motion of object that is blocked.
The converging motion of time-space at center is accelerated one. So, the object that follows it gains the same acceleration, then kinetic energy and momentum.
Any object or body that has three properties may be called free one. For example, gyroscope, spacecraft and instrument in it and Moon that can be seen as free object relative to the Earth. .
Obviously, here a very simple experiment demonstrates that falling object is the direct result of the converging motion of time-space or field at center, not gravity. The mechanism of falling object is the touchstone to test gravity and general relativity theory. My observed result and theoretical discussion may be a complement to Newton’s theory.
