What is the relationship between motion and gravity

Is gravity a result of movements (Rotation/Revolution) of cosmic bodies (including stars and galaxies, even as a passing fast-driven vehicle 'tries' to pull you towards it)? Should this be a layman's idea of what gravity is?

As I explain in my book, gravity is a n electronic wave which is generated and emitted by every atom in its "normal" state. It is possible to negate this wave emission so that a mass will lose its "weight" and inertia. This is thoroughly explained in the book. This technology lies in the realm of advanced quantum physics and is explained without mathematics for the lay reader.
Rotation and revolution are entirely separate matters and are only remotely related to gravity,. Rotation depends upon inertia and if you were to subtract inertia from a rotating body, it will perhaps cease to rotate and behave in a bizarre manner.
It may also rotate at a higher rate of turn... it is unpredictable.
In such a state matter is highly susceptible to influences of the mind and thought.

There is no relationship. The gravitational pull of an object remains exactly the same no matter what its speed.

The gravity of an object is the direct result of the amount of its mass and its force changes inversely by the square of its distance.

Gravity is a result of mass, not of motion.

A passing vehicle tries to pull you due to the reduced air pressure behind the vehicle, it has NOTHING to do with gravity.

Gravity seems to be a property of mass. If you travel at a large fraction of speed of light, you will gain mass.
The attraction you feel when a vehicle passes you at high speed is a lower air pressure effect.
