升台球技术需了解物理知识

很多人打台球只专心于技术练习,很少人会了解台球被击打后移动与物理知识联系到一块,其实所有台球被击打后的移动都符合动量守恒定律。其实我们手中的台球杆就好比一根链接台球技术与知识之间的杠杆,要想提高台球技术,我们需要平衡这根杠杆,所以物理知识还是要普及一下,有助于帮助大家在台球方面有更好的造诣。

A lot of people play billiards only with technical exercises. Few people know that the movement of billiards is linked to the physical knowledge after being hit. In fact, the movement of all the billiards that are hit conforms to the law of conservation of momentum. In fact, the billiard lever in our hands is like a link between the technology and knowledge of the billiards. To improve the billiard technology, we need to balance the lever, so the knowledge of physics is to be popularized and help you to have better attainments in billiards.


首先拿直线球来说,当目标求被击打后,这时母球将自己的动量全部传递给了目标球,如果母球没有旋转,那么这就是定杆,停在原地。有些朋友发现,当直接打母球中间时,为什么目标球还继续走, 原因是产生了台尼摩擦效应,让母球产生了前旋转。所以通过台尼摩擦效应我们就能得到经验,有点距离的球,我们要选择定杆,需要对准母球中下一点来击打,用来抵消摩擦。
First, take the linear ball, when the target is hit, then the ball passes all of its momentum to the target ball. If the ball does not rotate, it is a fixed pole and stops in place. Some friends found that when the ball was in the middle of the ball, the target ball continued to go on, because of the tribological effect of the table, which gave the ball a forward rotation. So we can get experience through the tribological effect of the table, the ball in a little distance, we have to choose the rod, and we need to aim at the next point in the ball to counteract the friction.

如果出杆旋转少,不管母球向前还是后,位移都相对于很少,所以要让母球走得快,就得加强旋转,无论是高杆,低杆,都是这样的道理。stun就是让母球的旋转少,中高杆stun,中低杆stun,中杆stun,都是属于stun。
If the rotation of the rod is less, the displacements are relatively small regardless of the ball forward or after the ball, so to make the ball go faster, it is necessary to strengthen the rotation, whether it is a high pole or a low pole. Stun is to allow the rotation of the ball less, the middle high bar stun, the middle low pole stun, the middle pole stun, all belong to stun.

对于有角度的击打目标球,其实也符合动量守恒定律,母球的动量分成了2个方向的矢量, 这2个方向的矢量和等于母球的原始动量。笔者打个比方,打薄球的时候,目标球所得到的动量非常少,母球本身动量基本还在,所以母球速度几乎没有减少。
The angle of the target ball, in fact, also conforms to the law of conservation of momentum, the momentum of the ball into the 2 direction of the vector, the 2 direction of the vector and equal to the original momentum of the ball. For example, when the ball is thin, the momentum of the target ball is very little, and the momentum of the ball is basically the same, so the speed of the ball is almost not reduced.

母球走弧线时,是两个力的合成。一个是分离交的动量,另外一个是母球的旋转产生的力。最开始,分离交的动量很大,旋转的力小,所以先偏移,然后旋转的力效果出来了,就会改变方向。
When the ball is in the arc, it is the synthesis of two forces. One is the separation of momentum, the other is the force generated by the rotation of the ball. At first, the momentum of separation and intersection is very large, and the force of rotation is small. Therefore, first offset, then the force of rotation will come out, and the direction will be changed.

话说回来,我们很多时候要打小低杆,纯低杆, 其实目的就是要让分离角的力小,旋转的力大。这样才是纯低杆,希望大家自己好好体会。
In other words, we often need to play a small rod, a low bar, but the aim is to make the force of the separation angle smaller and the force of rotation larger. This is the pure low bar, I hope you can experience it well.
