It is a false belief.
According to Newtonian physics, the only thing that causes a cue ball to not be at rest anymore is the impulse vector applied to the face of the cue ball, which has been measured and observed many times with high speed cameras to last less than 1ms. Math agrees. The human body can not generate forces within this short period of time, period.
This means that the impulse vector is the ONLY variable you have to work with. A three dimensional vector is an arrow in space and has the following components:
Position of the Head of the arrow (location)
Length of the tail (magnitude)
Angle of the tail (pitch/yaw)
Therefore the motion of the cue ball is completely determined by:
Tip contact point location on face of the ball the instant the cue tip arrives
The angle of this force
The magnitude of this force.
These can’t be changed during contact.
Fluid mechanics of the air affects things slightly, but it so small it is negligible.
General relativity affects things slightly, but it is so small it is negligible.
Quantum mechanics affects things slightly, but it is so small it is negligible.
The hemisphere that you were born in affects things slightly, but it is so small it is negligible.
You get the idea.
The delivery of the tip to a location on the face of the cueball is not part of this discussion. Its importance in application is isolated from the conversation, because observations of phenomena in isolation from application is exactly what science is.
There is a tendency of uneducated people to be desperate to know something that everybody else doesn’t. They have no credentials to reject an established theory of science based on experience, because their experience is not controlled.
Also, many in the pool player demographic / specific political circles, refuse to allow others to be smarter than themselves. It is called spiteful ignorance. Beware of this.
My credentials: masters degree in electrical engineering, physics focus, and over 10 years of focused pool ball mechanics research.
