帮我改下我的英文作文,
Seatbelts are the main safety measure in cars which are installed due to Newton’s first Laws.For example,a car suddenly stop the occupants of the car will continue to move at the same speed and in the same direction that the car was moving unless acted upon by an external force bringing passengers to rest in accordance to Newton's first law.The seatbelt acts as an external force bringing driver to rest in accordance to Newton's first law.If the driver is not wearing the seatbelt,they would easily to collide to the glass port,or fly out of the car,this as a consequence suffer life injuries or even death.Use an equation to show is that:A=V-Vo/t where V is the final velocity of the car and Vo is the initial speed of the driver which in this case is the speed of the car before braking.In accordance to Newton’s law,a force is reduced so will the force acting on the person as F=ma.
Airbag is an important safety,every time you driver your car,you are being protected by an airbags.From the Newton's first law acting as an external force and bringing a person to rest and that person is still travelling at the same speed and in the same direction that the car was travelling.The moment the sensor for the airbag detects a sudden deceleration,an electrical spark ignites the compound sodium azide inside the bag producing nitrogen gas and the bag inflates.
The airbag is designed to prevent important injury to the occupant’s head and chest and as soon as it is struck it begins to inflate at a steady rate thus preventing any bouncing and serious injury due to impact with it.This has the effect of bringing the person to rest over an extended period of time therefore reducing the amount of acceleration experienced.In accordance to Newton’s second law,as acceleration is reduced so is the amount of force acting on the person.

Seatbelts are the main safety measure in cars which are installed due to Newton’s first Laws. For example, a car suddenly stops,then the occupants of the car will continue to move at the same speed in the same direction that the car was moving unless an external force is brought passengers to rest in accordance to Newton's first law. In this case,the external force is provided by the seatbelt. If drivers are not wearing seatbelts, they would easily collide the glass port, or be thrown out of the car, this may lead to a consequence of suffering life injuries or even death. The equation below simply shows the theorical base: A=V-Vo/t where V is the final velocity of the car and Vo is the initial speed of the driver which is the speed of the car before braking in this case. According to Newton’s law, the resultant force is reduced so will the force acting on the person as F=ma.
Airbag is another important safety measure, once the car is being collided seriously,airbags will come up automatically to avoid direct collision. The moment the sensor for the airbag detects a sudden deceleration, an electrical spark ignites the compound sodium azide inside the bag producing nitrogen gas and the bag inflates.
The airbag is designed to prevent serious injury to the occupant’s head and chest and as soon as it is struck it begins to inflate at a steady rate thus preventing any bouncing and injury due to impact with it. This has the effect of bringing the person to the rest over an extended period of time therefore reducing the value of acceleration experienced. In accordance to Newton’s first law, as acceleration is reduced so is the force acting on the person.
改完了.主要改的是英语
理论硬伤如下：
安全气囊的保护的理论基础主要集中在：
1.避免直接碰撞造成的物理伤害
2.延长碰撞接触时间从而减少冲撞力（动量定律P=FT）
增加接触时间是主要理论基础.你要不要多提一下?
你那个安全带那里最好说一说.
安全带提供的力量是和MOTIVE FORCE相反的
所以你RESULTANT FORCE比较小.伤害随之也就少一点.
再者.a=(v-u)/t
SUVAT这个东西可以全部笼统地称为牛顿运动定律.
NEWTON`S MOTION LAW
还有.牛二定律是动量定律.
牛一才是F=MA.（外国人教材都这样,和我们国内的不太一样）
说完了.欢迎讨论.
好运~
