The difference between bow and crossbow:

　　1. Different pronunciations: the Chinese pinyin for bow is gong. Read it once, that is, the word "bow"; The Chinese pinyin for crossbow is nu. Read it once, that is, the word "crossbow";

　　2, the strokes are different: the bow is a simple pen, 3 paintings; The crossbow character is a multi-stroke character with 8 paintings;

　　3. The meaning of the word is different: the word bow has multiple meanings. First, it refers to the instrument for people to shoot arrows or projectiles. Second, it refers to the bowstring of cotton. Third, it refers to the ancient tool for measuring land. Fourth, it refers to people hunching over. The crossbow refers to the ancient weapon that used the power of instruments to shoot arrows.

　　First of all, the shape is different. The shape of the bow is relatively large. The shape of crossbows is generally small.

　　Secondly, the launch forms are different. Bows are usually fired vertically, while crossbows are fired horizontally.

　　Finally, flexibility is different. The crossbow can delay the launch. After strung the string, aim carefully before pulling the crossbow machine. Once the bow is pulled open, it must be launched immediately.

　　The difference is:

　　First, the force is different.

　　The power of the bow depends on manpower, and the power of the crossbow is realized by machinery;

　　Second, the range is different. The bow has a short range, while the crossbow has a long range.

　　Bow and crossbow is an archery weapon, but they have the following significant differences:

　　1. Structure: The structure of bow and crossbow is different. Bow is an elastic weapon, which consists of bowstring and bow arm. The strength of archery comes from the muscle strength of archer holding bow. The crossbow is a mechanical weapon, which consists of crossbows, crossbows, strings and mechanical components. The power of archery comes from the power of twisting the crossbow.

　　2. Strength: Due to different structures, crossbows are more powerful than bows, and they can launch more powerful arrows and have a longer range. The strength of the crossbow is provided by the crossbow machine and chords, and the shooter does not need to use his own muscle strength, so he can shoot arrows more accurately.

　　3. Usage: Due to the different structure and strength, bow and crossbow has different usage methods. Using crossbows requires some special skills and training, such as mounting crossbows, aiming, pulling crossbows, etc., while bows require archers to have high muscle strength and skills and patient training.

　　Generally speaking, crossbows are more powerful than bows, with longer range, better flexibility and speed, but their complex structure and use require more time and experience, and there are restrictions on their sale and use in some areas.

　　Bow and crossbow are two ancient archery weapons, and there are some remarkable differences between them. The following are the main differences in bow and crossbow:

　　1. Working principle: The bow is made by stretching the bowstring backwards, then pushing the bowstring forward quickly, and shooting the arrow by using the rebound force of the bowstring. The crossbow uses the mechanical structure to pull the bowstring to a specific position of the crossbow arm, and then release the trigger, so that the crossbow arm generates ejection force and shoots the arrow.

　　2. Manufacturing process: The bow is relatively simple to manufacture, mainly made of wood, bamboo or horns. However, the manufacturing process of crossbows is complicated, and it is necessary to use metal, wood or other materials to make crossbow arms and crossbows.

　　3. Range and speed: When the bow is launched, the arrow has less air resistance, longer range and faster speed. When the crossbow is launched, the arrow is subjected to large air resistance, with relatively short range and slow speed.

　　4. Preparation for launching: The bow needs to be stretched and wound before launching. Before launching the crossbow, it is necessary to pull the crossbow string to a specific position of the crossbow arm and aim it.

　　5. Accuracy: bow and crossbow has some differences in accuracy. The shooting range of the bow is large, which usually requires the shooter to have high skills and experience. The shooting range of crossbow is small, and the accuracy of shooting can be improved by aiming in advance.

　　6. Operation difficulty: Compared with bow and crossbow, the operation is more complicated, which requires the shooter to master certain skills. Due to the complicated structure of crossbows, faults may occur during use, which requires a high level of maintenance.

　　In a word, bow and crossbow has some differences in working principle, manufacturing process, range, speed, launch preparation, accuracy and operation difficulty. Bow is suitable for close combat and quick response, while crossbow is suitable for long-distance combat and protracted war.

　　Bows are generally simple and light, and they need to be launched by manpower, with short range and low power. Generally, crossbows are supported by the machine-enclosed technique. Just put the arrow into the arrow slot, then aim at the target and press the switch. It has a long range and great power, but it is heavy and expensive to manufacture.

　　Bow and crossbow is two different ejection weapons, and there are many differences between them.

　　Structurally, the bow is composed of elastic bow arm and tough bow string, while the crossbow is added with mechanical devices, including crossbow, crossbow arm and crossbow machine.

　　From the launching form, the bow and arrow are launched vertically, while the crossbow is launched horizontally.

　　In addition, the bow and arrow can be full of heavy arrows on the bow, or half of them can be pulled to shoot light arrows, while the crossbow is basically shaped after forming, and the range, initial velocity and penetration of the arrow have been fixed.

　　The crossbow is very powerful and can even be used to defend the city, but it has short range and low firing rate.

　　Bows and arrows are divided into soft bows and hard bows: soft bows have high firing rate, but low power and short range, and are usually used by cavalry; The hard bow has a low firing rate, but it is powerful and has a long range. It is usually used by infantry. China used compound bows in ancient times, especially in the Yuan Dynasty. This kind of bow combines the advantages of soft bow and hard bow, and has good firing speed, power and range. It left a terrible memory for the heavy cavalry in the west. Crossbow is a variant of bow and arrow, which is characterized by short range, low firing rate and great power.

　　In ancient times, crossbows were forbidden to use. Because the operation of crossbow is very simple, it does not need shooting skills, and it is easy for civilians to master its use. When loading a powerful crossbow, the shooter must step on one end of the crossbow with both feet, pull the string to the position of the transmitter with both hands, then press and release the crossbow, and then aim at shooting. It can be seen that the power of crossbows is serious. Later, there was a crossbow gun, which was used for siege and defense, as well as ancient naval battles.
