1.
2. Very good. Public hospital, Grade 3A, with its own health management center, is the best physical examination center in Zhuzhou.
3. Regular physical examination is about a hundred yuan. You can consult their physical examination center for specific expenses.
4. First of all, it is clear that the main difference between conservative force and non conservative force is that the work of conservative force has nothing to do with the path that the object moves through, but only with the position of the starting point and the ending point of the moving object, and of course also with the nature of the conservative force field; The work of non conservative force is not only related to the position of the starting point and the ending point of the moving object and the nature of the force field, but also related to the path of the moving object
for example, since the work done by the non conservative force is related to the path of the moving object, if the object goes around a closed path, the non conservative force does work on the object, and the work done by the conservative force is always zero. Non conservative force is also known as "dissipative force". For example, human cart works by overcoming friction, and friction is non conservative force.
forces that work on paths are called non conservative forces. The common friction force and the impact force of inelastic collision between objects are all non conservative forces. The non conservative force has the characteristic that the work along any closed path is not equal to zero
Add: because the work done by friction is related to the path of the moving object [that is, the distance of moving in the direction of the force]
respondent: Fengli University - grade 12 2010-4-2 09:2
the above answer is correct
supplementary question: non conservative force is the effect of force, which is not only related to the head end position, but also related to the path. So, the effect of friction is related to the head end position and path? Why
questioner: mrkpur
let me say a few more words, because the direction of friction is always in a straight line with the direction of relative motion or relative motion trend of the object, so as long as the object has relative motion or relative motion trend and the contact surface is not absolutely smooth, the friction will continue to do work, With the accumulation of relative motion or relative motion trend, the work done by friction is also accumulated, which means that each very short (differential) time period corresponding to friction has its "independent" work "displacement
if the relative motion or relative motion trend always occurs in a straight line, and the friction force (size and direction) is constant, then the work done by the friction force can be calculated according to the displacement of its initial and final position
on the contrary, it can't, just because of the problem of "independent" displacement, the combined displacement can't be used to replace the accumulated displacement of friction when doing work in the path.

Each person's physical condition is different, and the project is also different. I'll show you the network map and ask you some questions carefully
6. It must not be an elastic collision. For example, in the process of a bullet passing through a block of wood, there is relative motion between the bullet and the block of wood. Friction must do work to convert part of the mechanical energy of the system into internal energy. So it must not be an elastic collision.
7. It is recommended to go to the central hospital or the traditional Chinese medicine hospital. The physical examination centers of these two hospitals are relatively comprehensive
our enterprises basically choose these two hospitals
of course, if you have other hospitals nearby, you can also choose
basically, the general hospitals above grade 2A all have physical examination centers
and you can also choose which items for physical examination according to your own needs

8. Hello: according to your description, general formal public hospitals can have physical examination, so don't worry too much. Do not eat in the morning before the physical examination, so as not to affect the results of the examination. Physical examination is mainly blood test, check liver function, ECG, weight, leucorrhea routine, gynecological B ultrasound, colpos, etc.
