Bush hide shoes students to emulate such a study physics knowledge

Times News yesterday afternoon, Hangzhou youth Middle School East the new Park campus started (2), the students have to do a simulation: restore "Iraqi reporter threw his shoes, Nike Free Run, Bush hid the shoes" of the scene. In this class, under the auspices of the the squad leader Shizhou Wing Sports the members Qianchao Ming and science teachers how lei as an analyst, explore hidden among the "throw" and "hide" scientific knowledge. Experiments, a lot of the boys volunteered to play Bush, think about try not agile and Bush.Ultimately, however, Hu Hao day and Mouhao Jie was chosen as the experimental representatives.First round: shoes spinning in the air, Hu Hao day play an Iraqi reporter, Miu Haojie play Bush, both about five meters away.For to avoid students Dodge failed, how lei specifically looking for a helmet wear "Bush". "Reporter" right hand picked up the toe of the shoe, force threw.I saw the shoes in the air turned a few somersaults, "Bush" and quickly left flash, shoes and dropped to the ground. Qianchao Ming Hu Hao Day effort, Mou Haojie flash quickly, Nike NZ, which is the lead did not hit the two decisive factors. But He lei teacher said, this throw, throwing members did not take parts of the center of gravity of the shoes, the shoes rotation, extend their shoes in the air reaches the "Bush" face time, to reduce the probability of hit. Second round: shoes fall behind "reporter" Hold the parts of the shoes near the heel, fling firmly holding his right hand, raised high shoes."Bush is just down a squat, shoes fell behind him. The money tide ming Reviews throwing motion is very beautiful, but did not grasp the point of view. He lei agree with this statement: "throw out the movement speed of the shoes in the horizontal direction.Throwing member is quite hard, but the shoes throw too high, and will extend the time. ' Third round: shoes hitting other students two students to swap roles. Nike Air Max, The Miu Haojie the play "reporter" holding the shoes eyes Miaole Miao "Bush" have to pound each other straight.But "Bush" squatting escaped shoes hit "Bush behind classmate Wang Shi. He lei analysis is that, this time, the perspective of "reporters" force on force well, increasing the possibility of hit, but throwing the intensity is relatively small, slow speed, "Bush" easily escaped. The money tide Ming added, Miao Haojie aim was accurate, but the goal of aiming for too long, does not meet the case of news events. Fourth round: Dodge fail suddenly fling shoes hit "reporter" right hand grip shoes, shoes whispered rapidly fly "Bush", although the other party, or with just body leftist squat "position to escape, but this time no escaped being hit. He lei that, this time, "reporter summed up the experience of the previous, throwing all have a good grasp on the efforts angle shorten shoes thrown out to the landing time, so easy to hit. Aggregate resignation: This is a physical "Projectile Miu Haojie Hu Hao Day, by experiment, summed up best to avoid the program: body tilted to the left, quickly squat, and cover your face with hands folded.
