Using outside english has the CB "rolling" off the object ball while inside english has the CB "rubbing" off the OB.
Try to envision this experiment using people. Have someone stand to your left and slightly ahead of you, still, with their arms at their sides.
Slowly walk toward the person while spinning yourself counter-clockwise as you contact their shoulder as you pass by. (outside english) You hardly move the person except for a half twist in a direction opposite where you came in contact with them.
Now do the same thing, only as you walk toward them spin your body clockwise, ( inside english) The rub is much harsher as you pass.
I used this analogy on my kids a hundred years ago when they were young and I was trying to explain pool to them. It seemed to click as an explanation,
Maybe silly, but it is a dynamic way to illustrate the effect.
With the opening break in straight pool, using spinning outside english helps prevent the rack from what I call tearing apart and rather has the two end balls roll out and back more effectively.
This tearing IMO with inside english (skid) is caused by the CB forcing the OB to turn in the direction of the CB rather than allowing the CB from running away from the contact ball.
