Why the flying plate through reverse castor can only produce translation? What's the mystery bottles rolling downhill race? These is no extracurricular small problem sets, but 20 physicists 13 years American youth championship title. This year, shenzhen middle school team beat the U. S. teams, won the race to become the first team in China. Pressure-pad-force team beat the elite 'any doubt people in today's high school students enthusiastic about science, it must be without the experience of the tournament. 'The American young physicists, tournament organizers G regJacobs is a middle school physics teacher in the United States. Launched by his this competition, held once a year. Each year the problem released a year in advance, there is no standard answer. Students can use the basic equipment through a variety of ways to study of the problem. Teams this year, for example, to study is one of the problems of two kinds of caster wheel scooter and flying turtle.
