1. You can take a bus to humen or Dongguan terminal, and take a bus to Conghua. Shenzhen Overseas Chinese community bus station also has cars. It's supposed to take hours.
2. There is no direct train. Most of the information on the Internet is about the special bus in Luohu. With "car network" to facilitate your inquiry. The above is purely personal opinion. http://www.zuoche.com/traffic/
3. It's not the friction of the air, it's the friction of the object in the air. The friction coefficient of different surface states of the object will be different

5. The air resistance FW is a kind of reverse force formed by the air on the moving car, and its calculation formula is: FW = 1 / 16 · a · CW · V2 (kg)
where: V is the driving speed, unit: M / S; FW = 1 / 16 · a · CW · V2 (kg)
where: V is the driving speed, unit: M / S; FW = 1 / 16 · a · CW · V2 (kg)
where: V is the driving speed, unit: M / S; FW = 1 / 16 · a · CW; A is the cross-sectional area of the vehicle, unit: M2: CW is the drag coefficient
the air resistance is proportional to the square of the speed, that is to say, if the speed is doubled, the resistance of the car will be tripled. Therefore, the impact of high-speed driving on the air resistance is very obvious. When the speed is high, the engine will use a considerable part of the power, or fuel energy, to overcome the air resistance. In other words, small air resistance can not only save fuel, but also achieve higher speed under the same engine power. In addition to the speed of the car, the air resistance is also related to the cross-sectional area a and the drag coefficient CW
the drag coefficient CW is a non unit value. It describes the shape of the car body. According to the shape of the car, the CW value is generally between 0.3 (good) and 0.6 (poor). The smooth body shape (the most ideal is the water drop type) makes the velocity of the air flow through the body change little, does not form vortices, and the CW value is low; On the contrary, if the body shape has edges, corners and seams, the CW value is high. Generally speaking, the wheels of racing cars are designed outside the car body to form a whole. Theoretically, the CW of each vehicle can be measured in the model making stage, but the accurate CW value must be obtained through wind tunnel test after the finished proct is proced
by improving the aerodynamic performance of the car, such as changing the tail, chassis cover, front air inlet and hub cap, the drag coefficient can be reced. Recing the height of the car body is equivalent to recing the cross-sectional area, or making the car cover the wheels more, which is also concive to recing the air resistance<
= =
air resistance.
the air resistance is directly proportional to the speed of the object movement, that is, f = kV
k is the air friction coefficient, which is related to the air density. In the place where we can find something to throw, it can be generally considered as a constant.
when the object starts to fall from the air, V is very small, f is very small, Mg & gt; f. So the object accelerates graally. With the increase of velocity, f increases, and finally reaches the equilibrium point of Mg = F. at this time, the object begins to fall at a constant speed. And we know that the falling rate is v = mg / K. in the general sense, what we call weight is mg

6. The air resistance FW is a kind of reverse force formed by the air on the moving object,
its calculation formula is: FW = 1 / 16 · a · CW · V ^ 2 (kg)
where: V is the moving speed, unit: M / S; A is the cross-sectional area of the object,
unit: M2: CW is the drag coefficient
the air resistance is proportional to the square of the velocity
then
can be obtained from the moment balance:
L ∫ fwdr & # 39
= fr
integral interval [- R, R]
and FW = L / 16 · CW · R & # 39^ 2w^2
l∫1/16·cw·r'^ 2w^2dr'= Fr
1 / 24 * lcwr ^ 3W ^ 2 = fr
F = lcwr ^ 3W ^ 2 / 24R
CW can be obtained by empirical data (generally by looking up tables)
