Mechanics of playing football

Do you need to understand physics and mechanics to play football
Some understanding is required, such as the trajectory of the ball, which involves physics. But it doesn't matter if you don't understand it. Some people are born with good foot feeling and don't need to calculateWhat are the ways to improve strength and speed in playing football
Do sit ups, exercise waist strength, and do 100 every day. The 25 meter turn back run is the best way to exercise your explosive power. 10 groups per day, 5 times per group. Sprint, not jog. When practicing weightlifting, don't pursue weight. As long as the appropriate barbell is important, you can lift it 100 times a day. LeapfrogThe mechanics principle of football stopping

The principles of scientific knowledge used in playing football. Great gods help
Mechanics for shooting and passing, friction for running, aerodynamics for curvilinear ball, heat for sweating and fever for running, electricity and radio electricity for live broadcast of football matches, many players taking illegal drugs, involving chemistry, and medical treatment for injured players, involving medicine, such asMechanics and free kick technique in football
This force is proportional to the velocity difference between the two sides of the body. It's just like the principle of taking off. In short, the faster the rotation speed of the football, the more the trajectory of the football deviates from the straight line; But if you want to kick a beautiful and effective banana ball, it is also related to strength, distance and wind directionWhy doesn't playing football have anything to do with the effect of force
Because pure mechanics is only used for theoretical research. After all, there are other factors such as air resistance and wind direction in the process of football. The friction force of a football rotating at a high speed will change the direction of motion, which requires very complex calculations
On 'the physical and mechanical principles of kicking a curved ball (or banana ball) "
In fact, football has more than " Banana ball "e;, Table tennis, volleyball, tennis, etc. all use the rotation technology to create various erratic and mysterious strange balls, such as the circle ball in table tennis and the floating ball in volleyball, which are all created based on this principle. The principle of banana balls is based on aerodynamicsBiomechanical principle of long pass with big foot in football
Use the inner instep, the part connecting the foot thumb and the foot arch, that is, the slightly protruding part of the bone, to exert force towards the lower 1/3 of the football. Pay attention to the direction of your body and the force direction of your feet. Or directly use the upper part of the arch of the foot, the joint with the ankle, that is, the upper part of the instep, less inclined to the inner side of the bodyWhat physical knowledge does basketball and football contain
Momentum theorem, kinetic energy theorem, law of conservation of energy, relationship between acceleration and velocity, Newton's first, second and third laws, law of universal gravitation, circular motion
Why put forward the biomechanical basis of thigh driving calf when playing football
According to the momentum theorem, in order to give a strong impulse to an object, it is required to give the object a short contact time. Before playing football, the thighs are swung successively and the legs are bent. These actions can not only save labor, but also increase the working distance when playing football and prolong the action time of muscle strength. Before playing football, the thigh back swing lengthens the length of the thigh bending muscle
