English and caroms

[bbb]

i know that draw on the cue ball translates to follow on the object ball so
so if you hit the object ball with draw it will travel foward of the tangent line of the carom off the second object ball
follow on the ceu ball would do the reverse
i hope thats correct
my question is does english on the object ball also influence to some degree how the object ball comes off the tangent line when striking another ball ie on a carom shot im referring to?

whats you opinion???

All balls of equal mass and diameter are subject to the same laws of physics. Therefore it doesn't matter which ball strikes another ball whether it's a cue ball striking an OB or an OB caroming off another OB. As long as the speed and spin are identicle, at the moment of contact, the results are the same.

The main distinction is that the cue ball may have draw and transfer top to the OB. If the first OB then strikes a second OB, it will carom off the second OB with whaterver level of top spin is on the OB at the time of contact.

The level of draw on the cue ball will not transfer an equal amont of top spin to the OB. Keep this in mind when you try to calculate the amount of spin in the first OB as it collides with the second OB.

So you're hitting a cueball into an object ball that is then caroming off a second object ball, right?

By far the biggest factor in determining whether the first object ball bends forward of the tangent line is the topspin it picks up from friction with the cloth on its way to the second object ball.

appreciate the responces ^^^
but in another thread it was implied that english could augment or detract from the follow or draw
i had never heard of that

Does this also depend on the distance between the cue and the first object as well as (if not more importantly) the distance between object #1 and object #2? Do you really have to stoke the cue a lot to see a noticeable effect of follow or draw on an object ball, especially when you are using follow? Doesn't the friction of the cloth counteract the object ball's tendancy to pick up back spin from a cue that was hit with follow? Does the use of follow on the cue slow the object ball after contact? Does the object ball slide after contact with a cue that was hit with follow and, conversely, immediately start rolling after contact with a cue that was hit with draw? Either way, if the object 1 has far to travel to get to 2, wouldn't it be rolling, and thus have the same effect on #2? (strictly draw and follow if that were possible)

Also depends on the angle of impact between cue and #1 too because won't that determine the spin imparted on object 1 that will transfer to 2?

Not sure how much of a hijack that was, but I was always wondering. Good post and sorry for the machine gun question style.

A small amount of spin can be transferred from the surface of the cue ball (or other incoming ball) rubbing on the struck ball. This effect is absolutely crucial to making bank shots but it has a relatively small effect in making an object ball carom off another object ball. As Mike Page pointed out, the majority of top spin on an object ball will be from rubbing on the cloth between the cue ball and whatever the object ball hits.
