Tangent Line

You have a 10 degree cut and you hit it at speed A and it travels down the tangent line.

Then say you have a 40 degree cut shot at the same distance and you want it to go down the tangent line so you hit it at the same speed A.

Is this possible hitting the same speed?

In other words, as the cut angle of the shot increases do I have to hit it slightly harder for it to travel down the tangent line?

Thanks Devindra
 
It'll always travel in tangent lines as long as you hit with no spin. Hard or soft doesn't matter.
 
Not quite sure Im following you completely..... but if the ball is sliding at contact it will travel on the tangent line. No matter the speed. Now, on a thinner cut, the cue ball beginning to roll forward will be more visible than on a thicker cut at the same speed. The reason is the length of travel.
If you hit that 10 degree cut at a soft speed, but with stun so that it arrives at the objectg ball with no spin, and goes down the t. line, it will travel a certain distance before it stops. If you hit the same speed on the 40 degree cut, the cue ball will travel farther than before, giving more time for the ball to start rolling forward naturally, because of the thinness of the hit (the collision wasnt solid enough to take as much speed off of the cue ball).
Hope this helped?

yes, it will go down the tangent line, but with a thicker cut, less speed is retained (retained speed moves the cue down the tangent line) in the cue ball, so it won't move as far in that direction. in addition, the thinner the cut, the more the follow developed from rolling (if you hit it soft enough to not be skidding when it contacts) is pointed towards the tangent line, so the cue will tend to go more towards the tangent line. the thicker the cut, the more the follow fights the tangent line.
 
The tangent line always applies as long as the CB has NO spin (regardless of the angle of the cut). This can be achieved 2 ways:

1) Hit the ball hard. This means the the CB is still sliding upon contact, and any spin it has will not take effect. The CB will travel down the tangent line (until it slows down and the friction from the cloth catches).

2) When shooting at a slower pace, apply stun/stop to the CB to mimic the above sliding effect. For closer shots youll usually need to hit the CB a touch below center. As the distance between the two balls increases, you'll need to strike the CB lower to get this stun/stop effect, which over long distances might require actual backspin. By the time the two balls collide, the backspin will have worn off, resulting in the intended stun/stop shot.....which will once again send the CB down the tangent line.

Hopefully that made sense. I explained it 23432 times better in my movies (Lesson 14 on Volume 1 & lesson 16 on Volume 2).

EDIT: Watch the middle of Lesson 13 here. It goes over some of what I just said www.mastering-pool.com/samples.html

Devindra...Lots of good advice in this thread. Bottomline...as long as the CB skids into contact with the OB (meaning it is NOT rolling at contact), the CB will leave on the tangent line, regardless of cut angle (the tangent line will be appx. 90 degrees from the cut angle contact point). How far the CB travels down the tangent line will depend on several factors, stroke speed being the biggest one.

[Others have given good answers. This is just in case hearing it a slightly different way helps.]

Yes. As others have said, you just need to hit the OB with a stun hit (like a stop shot) in order to keep the CB on the tangent line. In your case (shooting from the same distance) you can hit both shots at the same speed and the same vertical tip offset.

In other words, as the cut angle of the shot increases do I have to hit it slightly harder for it to travel down the tangent line?

The cut angle doesn't matter - it only matters that you hit both with stun.

with regards to cut angle, lack of stun, and perceived tangent line, my post has a good explanation.
