What's the difference between badminton's killing weight and killing speed?

I have always been puzzled about this question, because the physical basis should know that if the weight means that the racquet surface is in great contact with the ball, then the momentum of the force should contact the badminton, which is equal to the mass multiplied by the speed, and the badminton with the same mass is a constant. According to this definition, the range is directly proportional to the speed of the ball. The same badminton should not have "I killed more than you, but you didn't have a fastball". However, in the general discussion of badminton killing, there is often a contrast between killing weight and killing speed, which shows that the definition of weight and speed here may be different from the previous understanding. Either weight doesn't mean fast, or fast doesn't mean fast. Semantically speaking, weight is usually related to strength, so I tend to think that weight refers to the force on the racket face when hitting the ball. As mentioned earlier, this power relationship is consistent with the speed of the ball. So the weight should be equal to the speed of the ball. What do you mean so soon? In order to rationalize this problem, we can also consider what speed is usually related to. Indirect, the concept of speed can be understood as that it takes less time to achieve the same degree of completion. For example, if you run fast, it takes less time to run the same distance. Eating fast means eating the same amount of food in less time. Growing fast means growing to the same weight or height as others in a shorter time. According to these two quick readings, I think this means that it takes less time to kill the ball. The process of killing the ball does not refer to the process of defeating the ball and then landing, because if we only refer to this process, the short time of this process is equivalent to the faster the ball flies, which is the weight mentioned above.

Here, I think it should be understood that it takes a short time to kill a player, from when he sees the ball and starts playing, to when he finally drops the ball or hits the racket face. The shorter the process, the faster the killing speed. So you can see the difference between fast and heavy, although they both mean short time, and the weight is determined by the speed of the ball, so this means that when the ball is on the same trajectory, it stays in the air for a shorter time; Fast means that under the condition of the same sports composition, the time of hitting and hitting the ball, plus the time of flying the ball in the air, will be shorter. So it is not difficult to understand that in some cases, speed and weight should be related. Relevance is a necessary condition for being neither heavy nor heavy, and very fast is a sufficient condition for being heavy, because fast not only takes a short time from the beginning to the swing, but also takes a short time to make the ball fly. Very fast. The flight time is short. If you want to kill the ball, it has nothing to do with the length of the swing (you can't say no, at least before hitting the ball, with strength, the swing ball is getting faster and faster). As long as you hit the ball face to face, the instantaneous linear speed is faster than others. So, which is more deadly, weight or threat? From the above definition, I think it is more dangerous to kill the ball quickly. Because when killing the ball and killing the ball, their relative positions are fixed, and the crushing of killing the ball, at the same time, the difficulty of catching the ball depends on the time from the death of the body to the reaction of receiving the ball. In this process, as well as the length of this time, it is necessary to clarify the relationship between killing the ball and landing from the beginning. After all, the physical reaction of the recipient should be formed after the recipient is activated.

So, if you have two such people, one person kills the ball quickly, but it takes a long time from the beginning to his swing; The other person, although not as fast as the last one, has a shorter total time from starting to hitting the ball to landing because of his consistency of speed and technology. So I think it can be said that the former kills the ball heavier than the latter, and the latter kills the ball faster than before. Generally speaking, the latter is more likely to win the opponent's score by killing the ball. This is my personal understanding of this problem, hoping to give you some inspiration.
