It is said that if physics is good, billiards will be played well?

Billiards must be good if you have good physics, in fact, it is a kind of ridicule, mainly to ridicule billiards that you need to apply a lot of mechanical principles, in fact, in addition to physics, billiards is played well, and it is also related to many factors, such as physical strength, strength and endurance and so on.

It should be very helpful, because a lot of knowledge of physics can be close to life, and it can be used to calculate the strength of the ball and the arc of the parabola when used in playing billiards.

Billiards uses the knowledge of reflection, refraction, and the movement trajectory of the focal point in physics, so the good physics is very helpful for playing billiards.

Physical collisions can be divided into two types, fully elastic collisions and non-fully elastic collisions. The so-called fully elastic collision is an ideal collision, there is no energy loss in the collision, usually, we regard the collision between those hard objects as a completely elastic collision, such as the collision between steel balls, glass balls, steel balls and hard ground, etc. There is a loss of energy in imperfectly elastic collisions, which is also a common type of collision that we see.

When a non-perfect elastic collision occurs, if two objects collide together after the collision.

This type of collision is called a completely inelastic collision and has the greatest loss of energy, and both fully elastic and non-completely elastic collisions follow the law of conservation of momentum. The laws of conservation of momentum have a wider range of motion than Newton's laws of motion, except for the universe and the microcosm that interact in the interaction of elementary particles. Two objects collide in two forms, forward and obliquely.

For billiards, during the batting, according to the different positions of the main ball and the target ball.

Basically, the positive and oblique hitting mode is adopted, and in the striking mode of oblique collision, the angle of collision between the main ball and the target ball should be selected according to the need, which is a skill that must be mastered when playing billiards, according to the momentum theorem, the speed of the main ball after hitting the cue stick is related to the impulse of the cue stick to give the ball. The impulse of the cue club is determined by the force of the cue stick and the duration of the shot, in the momentum theorem, when the object is affected by the impulse i, it causes a change in the momentum p of the object.

Its expression is i δp, i.e., fδt δp, and in order for the velocity of the target ball to vary greatly, but the momentum change is determined, two basic methods can be employed. One is to apply a larger hitting force but a shorter hitting time by cueing, and the second is to apply a smaller hitting force but a longer hitting time through a cue to control the hitting force of the cue stick and the striking time to achieve it by controlling the cue.

Regarding the question of what scientific principles and physical laws must be understood if you want to play billiards well, I will explain it here today.

First, the theorem of conservation of momentum, the collision between balls follows the conservation of momentum. Second. In physics, the angle of incidence is equal to the angle of the ridge of the exit area, and you can choose the right angle by mastering certain skills.

The elastic collision and the incomplete elastic collision between the billiards game fingers follow the law of conservation of momentum, and two objects collide in two forms, forward collision and oblique collision. In the process of playing the god with the ball, the banquet slippery straight and oblique hitting method is basically adopted.

To play billiards well, the first thing to understand is the collision and movement trajectory of billiards, the elastic Yulu collision Yexi and the spine are non-elastic collisions, and the two balls collide in this different way, and the effect is different.
