Formula Ifs=1/2mv^2:
This is the formula for the transformation of work and kinetic energy.
In this formula, s refers to each person's physical condition, such as leg length, such as arm length, which is basically fixed, unless, you are still a developing child, and f refers to your strength.
Of course, the force here in high school physics generally refers to a constant force, and in college physics, it has been replaced by an integral form, but in any case, the habit of people punching and exerting force is almost the same, and the change trajectory of the force is basically the same, and the statement of increasing several times should barely be established.
Therefore, it can be seen from the formula that if your absolute power increases by 2 times, your ultimate speed will become 1.414 times at most, which is the relationship between the square and the square.
Equation IIh=1/2gt^2:
This is the conversion formula for the distance and time of the free fall, and of course it can also be said to be the conversion formula for the height and time of the object to the apex.
Here, h represents the height of your straight jump, so the acceleration is accelerated by gravity.
According to the formula, t=v/g, where v refers to the initial velocity of your upward jump, according to the formula I, you can know that it will be the square times of the force you are strengthening, and the gravitational acceleration never changes, so the time for you to jump straight up is also the square times of the force.
According to Equation II, the acceleration due to gravity is constant, time squared, so the height of your straight jump will be proportional to the reinforcement of your strength, if you don't count the air resistance.
In fact, the faster the speed, the more obvious the performance of air resistance, and when the human body runs in a straight line, the body does not conform to the principle of streamlining at all, and the influence of resistance is very large, so all the data will be much less than the theoretical data when it is written, and the larger the data, the more it will be lost.
Moreover, the speed of running in a straight line mainly depends on the friction of the soles of the feet, and it is not a concept to jump in a vertical jump, but it will be explained to this extent by high school physics. I didn't study physics well in college......
The data on the limits of human beings in the book are derived from these two formulas.
In short, the ultimate force ~ the ultimate speed ^2 ~ the height of the vertical jump ~ the time of the air ^2 (~ represents proportional to, too lazy to find the standard symbol).
Athletes' physical limit data: vertical jump 1.2~1.3 meters, running speed 10m/s, punch weight of about 300 pounds.
It is not the most extreme data, but it is taken from the relatively average level of athletes at the highest level, as for the weight of the boxing, it is said that the heavyweight boxing champion can reach the level of 450 pounds close to 500 pounds, however, not everyone has the size of the boxing champion, it is said that when Bruce Lee performed in the Canadian Boxing Association, there was a record of 350 pounds, which is equivalent to 160 kilograms, and he didn't need to be so ruthless, just count 300 pounds.
This is just a casual push when the layman is bored, if there is a great ability in this area, you are very welcome!
