1. The internal force in the building structure has nothing to do with the friction on the surface of the structure
the internal force of a building structure refers to the tension or pressure on the section of a member under the action of external force.

2. The so-called internal force is the force that can be offset by the integral method
the internal force and the external force are relative
for example, two objects in relative motion,
if you consider the force of an object in the period,
then the friction force is the external force of that object,
if you look at the two objects as a whole,
friction is internal force

3. The work in kinetic energy theorem includes the work done by all forces, all internal forces, all external forces and the total work done
4. The power comes from the speed of the bullet and the density of the wood block. For example, if you want to enter the water, the density is small, the friction force is small, and the internal force is small. I guess you're a liberal arts student. You don't know physics at all. You're a pure idiot
if you are really worried, just ask a primary school teacher tomorrow

5. In the use of the watch, the opening and closing of the buckle should be smooth, and the closing force and opening force of the buckle should be moderate. If the closing force of the watch buckle is loose, it is easy for the watch to be detached, so the watch will be damaged. If the buckle can't be closed, you can go to the after-sales center to replace it.
6. Watch strap belongs to consumables, especially leather watch strap. Even if the top crocodile leather watch strap is worn frequently, its service life is about 2 years. Exposure to sunlight and contact with sweat on the body can cause great damage to watch strap. Wet air or water is not handled in time, it is easy to make watch strap crack deformation, and there will be odor. Watch strap watch strap: watch strap
1, long term intense sunlight mapping, will make the leather strap color decolorization, accelerate the aging of leather strap cortex, some chemical test chemicals such as perfume will also make the watch strap color change or decolorization.
2. If you pull too hard when wearing the leather strap, it is easy to show cracks in the fixed position of the leather strap (the greater the buckling rate of the leather strap, the easier it is to break). Therefore, it is better to be cautious and gentle when wearing the leather strap
3. As with other leather items, the most taboo thing for leather strap is water. If it is immersed in water for a long time, the leather strap will become hard and brittle immediately, especially the sweat absorbed. Therefore, it is absolutely not allowed to snorkel (or do things that are exposed to water for a long time) with a watch with genuine leather strap. Long period of sweat penetration can also make the genuine leather strap moldy
4. To clean the leather strap, wipe the strap lightly with a moist soft cloth, and then dry it in a dark and ventilated place. Every 1-2 months, use the leather strap protector to wipe the strap, and then use the maintenance agent to wipe the surface, which can not only maintain the texture of the leather strap, but also improve the brightness
5. Don't fold the watch strap in half. In winter, the watch strap is hard. Don't "fold back" to damage the cortex.

7. Hello, it is suggested that you can open the warranty sheet attached to the meter. Under normal circumstances, there will be a service address and after-sales telephone number on the warranty sheet, or you can find a regular watch Service Center for inspection and maintenance, and the address of the exclusive store. If there is a professional after-sales Service Center nearby, it is also OK.
8. Daily maintenance of the dial
1. Watch water or long-term damp, it is very easy to ince the dial discoloration, or the dial cover varnish peeling off, which is characterized by the occurrence of more at the edge of the dial. Therefore, when wearing non professional diving wristwatch, try not to get wet, swim, etc
2. When a watch is placed or exposed to the sun for a long time, all kinds of rays in the sun will make everything slowly change color, and so are beautiful things. No one can escape. Try to keep the watch away from the sun.
