Quick question about Cut Induced Throw

[Amaury]

Hello,

when you cut a ball (for example 45 degrees) , does the object ball goes straight with an initial angle less than 90°, or does it start on the tangent line THEN does a slight curve?
I am asking because every time I pot a ball while compensating for throw, I first think I missed it and then the OB finally goes in. Just tell me if my eyes are wrong.

Thanks

sweepers wont do as the balls move too fast.

but a good trick is to go around and pick off lint from the table, while secretly dropping bits of something else to make the balls roll your way.

Please pool players, do not talk about electricity and electomagnetics if you do not have a degree. I really hurts those of us who actually know about the subject.

The electrical field though runs outside the wire right? Something about the actual energy...

OK, show us Dr. Dave's demo.

Here. Wasn't hard to find.

I’m familiar, but gaff shots with chalked contact points are the exception, not the rule.

Same principle.

FYI, this topic is covered and demonstrated in great detail here:

Object Ball Swerve and Turn​

Under normal conditions, an OB heads perfectly straight in the thrown direction. For more information and demonstrations related to cut-induced throw, see:

Probably what you are thinking of is when electrons move they create a magnetic field. The magnetic field is outside of the wire the electrons are moving through. Lots of cool ideas came from this discovery. Transformers are one. Electric motors another.

It was something stated in some article on pocket or a web science mag. Pretty sure electric shock was cited in that context too. Could be new thinking or bunk. IDK.

I think you’re confusing it with the fact that alternating current tends to flow along the surface of a conductor.

Here. Long video for a post but it does detail the process.

Um. This guy doesn't know what he is talking about. The first sign is he said "electrons in the power grid are just wiggling back and forth. they never really go anywhere." lol not even close to true.

Power lines have very high electrical fields (voltage) and very little current so the power lines won't lose a lot of voltage while traveling from point A to point B. Then at the end point the voltage is converted to current using transformers.

They guy in the video talks about breaks in the power lines. These are the transformers which use magnetic fields to do the transformation. In his long winded way, using some very strange props, he is trying to explain electromagnitism. All discovered by Maxwell in his 4 equations.

I don't know why he said everything we were taught about electricity was wrong. That is not true. Maxwell discovered all this, and it was put into many, many things long before we were born.

.... he said "electrons in the power grid are just wiggling back and forth. they never really go anywhere." lol not even close to true.

I think he got that part right. As I recall the discussion in one of my physics classes, aluminum (the main metal in long-distance transmission lines) has three available electrons per atom as a conductor. Each ounce of aluminum is roughly one mole, and a little calculation gives about 300,000 coulombs of charge available in that ounce. If the high-voltage line has 1000 amps (at maybe 500,000 volts) then the charge passing a point is 1000 coulombs per second. It would take 300 seconds for all of the charge in one ounce of aluminum to move to the neighboring ounce of aluminum. In half a cycle of 60Hz, or 1/120 second, the charge is going to move much less than an inch. The electrons are wiggling.

This tends to support what he said about electricity approaching C while electrons go nowhere. Bizarre stuff.

Yes/kinda/is/are the set of balls in use.... just been polished?

The feel of the cling release after ball collisions such as this are developed during play, before starting competition are.... considerations, the cue ball brand/mfg/weight. Have you used this brand before? If not Practice is Critical.....
During play....developing a feel for the the object ball contact clip/skid/spin reactions after cb contact win matches.
