In 1998, the World Cup in a penalty to be cruel way to determine the
coach bags. England lost on penalties again in the old rivals Argentina, in which Batty's penalty shot goal did not shoot people.
At this time, an English gentleman Delikelao Ph.D. (the world's leading nuclear experts), can no longer contain himself the hearts of anger. England football coach pick up a pen to write the following letter:
Hoddle Dear Coach:
Please allow a former candidate for the Nobel Prize in Physics (1994) set out to you with a simple principle of physics.
I am led England you know much about the situation, particularly the penalty of your training methods. But you lost to Argentina in this ball of view, you have a lack of some basic science concepts. England is due to ignorance and lack of education have been eliminated, but we really are a very high cultural level of the traditional country.
From the physics point of view, the highest success rate of penalty should be close to the ground flying into the door. A physical good goalkeeper can easily jump up or to the right and left, the ball kick it out. But when he hands down the net smash, he must be the focus of the rapid decline, while the hand moving down the speed of an average of only 32 feet per second (1 foot equals approximately 0.304 meters).
The
coach outlet of such movement by gravity, the speed and the speed of the ball very far forward setting, so close to the surface of the penalty is the goalkeeper saved the ball the hardest. However you choose Batty, Batty has opted for a low probability of success of semi-lob. Perhaps you do not believe that in the pati shot of that moment, I have felt that England's failure. This is a basic scientific knowledge, poor failure. If you feel that my description is a waste of time, then I would rather chat with my mother Qupei. She is soon 90 years old, they still insist on watching a football game ... ... although her health adversely. If you have been before the game a few simple mathematical analysis, or have had a little studied under mechanical, then you should be able to guide players play well every one penalty. In this way, Argentina is impossible to stay in France had.
Finally to you, for example, still remember Baggio's two penalties do? The last World Cup finals, he played the upper corner door, resulting ball fly. The Chilean team, he kicked a ball close to the ground, although the Chilean goalkeeper made a correct response. However, the ball can not be saved - the strength of his legs, not yet in tune with the gravity. Roberto Baggio penalty after the shoot will take this a correct scientific way.
After returning home, you and your team still with a good tutorial about the
cheap coach bags.
