Topic: It's hard to kill flies with your hands, but it's easy with a swatter – explain the reasons behind it
Reading guide: On a summer afternoon, mosquitoes and flies have become a nightmare at home. However, have you ever wondered why it is so difficult to hit a fly with your hands, but so easy with a paddle? This article will reveal the answer to this question and discuss the science. I hope that through the reading of this article, you can have a deeper understanding of this.
Chapter 1: Speed and Reflexes of Flies
As a master of flying in the insect world, flies are definitely not to be underestimated in terms of speed and reflexes. When we try to hit a fly with our hands, the time it takes for our arms to react and chase after the critter has exceeded the fly's reaction time. To put it simply, your strike speed is nowhere near as fast as the fly's dodge speed, so you'll have a hard time successfully catching the ever-changing fly.
Chapter 2: The Benefits of Using a Tempo
As a sharp weapon to repel flies, the advantages of the slapstick can be seen. First of all, the length and shape of the paddle is better suited for chasing fast-moving flies than the palm of our hands. Secondly, the speed and force of swinging the racket is greater, so that the racket has enough power to hit the fly. In addition, the large fan-shaped area of the paddle is able to cover a wider area, leaving flies with nowhere to hide.
Chapter 3: A Lever for Racquets Based on Scientific Principles
In fact, there is another important scientific principle that supports the fact that a slapstick can easily hit flies, and that is air resistance. When you try to hit a fly with your hand, due to the small area of your hand, the air resistance is correspondingly smaller, and it is easy for the fly to perceive and dodge in time. On the other hand, the area of the racket is large, and it can produce greater air resistance when waved, while the fly is not easy to detect the change of air flow in time due to its small size and special wing structure, so it cannot avoid the attack of the racket.
Conclusion: It is difficult to hit a fly with your hands, but it is easy to repel it with a paddle, and there is a decryption of scientific principles hidden behind it. The speed and reflexes of flies make it impossible for the hand to catch up, and the paddle makes up for this disadvantage, allowing us to easily solve the problem of flies through factors such as its length, swing speed and air resistance. Hopefully, through the elaboration of this article, you will have a deeper understanding of why it is difficult to hit flies with your hands, but it is easy to use a paddle.
