关于牛顿的英语作文

篇一：牛顿简介--中英文对照

1643年1月4日，在英格兰林肯郡小镇沃尔索浦的一个自耕农家庭里，牛顿诞生了。牛顿是一个早产儿，谁也没有料到这个看起来微不足道的小东西会成为了一位震古烁今的科学巨人，并且竟活到了84岁的高龄。

On January 4, 1643, in England, Lincolnshire town with PU cable of a self

cultivation farm family, Newton was born. Newton was a premature infant, who also did not expect this seems not worth mentioning little things will become an unprecedented scientific giant, and he lived to be84 years old.

牛顿出生前三个月父亲便去世了。在他两岁时，母亲改嫁给一个牧师，把牛顿留在文盲的外祖母身边抚养。牛顿自幼沉默寡言，性格倔强，这种习性可能来自他的家庭处境。

Newton was born three months before his father died. When he was two years old, his mother remarried to a priest, left Newton illiterate grandmother side support. Newton childhood be scanty of words, stubborn personality, this habit may come from his family situation.

牛顿的沉默寡言让他更喜欢思考问题，他种的苹果树慢慢地长大了；大约从五岁开始，牛顿被送到公立学校读书。少年时的牛顿并不是神童，他资质平常，成绩一般，但他喜欢读书，喜欢看一些介绍各种简单机械模型制作方法的读物，并从中受到启发，自己动手制作些奇奇怪怪的小玩意，如风车、木钟、折叠式提灯等等。

Newton be scanty of words make him more like thinking, he planted the apple tree slowly grown up; approximately from the age of five, Newton was sent to the public school. As a teenager Newton and not a prodigy, he qualified normal, average, but he likes reading books, like to see some introduced a variety of simple mechanical model making method of reading, and be inspired from, DIY strange gadgets, such as cars, wooden bell, folding lantern etc..

牛顿在中学时代学习成绩并不出众，只是爱好读书，对自然现象有好奇心，尤其是几何学、哥白尼的日心说等等。他还分门别类的记读书笔记，又喜欢别出心裁的作些小工具、小技巧、小发明、小试验。

Newton in the middle school academic performance is not outstanding, just like reading, the natural phenomenon with curiosity, especially geometry, Copernicus's heliocentric theory etc.. He also be arranged to record reading notes, and create new styles like the some gadgets, tips, gizmo, small test. 后来迫于生活，母亲让牛顿停学在家务农，赡养家庭。但牛顿一有机会便埋首书卷，以至经常忘了干活。每次，母亲叫他同佣人一道上市场，熟悉做交易的生意经时，他便恳求佣人一个人上街，自己则躲在树丛后看书。有一次，牛顿的舅父起了疑心，就跟踪牛顿上市镇去，发现他的外甥伸着腿，躺在草地上，正在聚精会神地钻研一个数学问题。牛顿的好学精神感动了舅父，于是舅父劝服了母亲让

牛顿复学，并鼓励牛顿上大学读书。牛顿又重新回到了学校，如饥似渴地汲取着书本上的营养。据说有一次，他去郊外游玩，之后靠在一棵苹果树下休息，忽然，一个苹果从树上掉下来。他觉得很奇怪，为什么苹果会从上往下掉而不是从下往上升？他带着这个疑问回到了家里研究，后来他通过论证发现原来地球是有引力的能把物体吸住。随后，就出现了《牛顿物理引力学》。

Later forced to live, mother let Newton suspended for farmers at home, raising a family. But Newton had the chance working roll, and often forget work. Every time, mother told him the same as a market, familiar with the trade business, he begged the servant of a person in Shangjie, he was hiding in the bushes after read a book.

Newton's first law

Main article: Newton's laws of motion#Newton's first law

Newton's first law of motion states that objects continue to move in a state of constant velocity unless acted upon by an external net force or resultant force.[10] This law is an extension of Galileo's insight that constant velocity was associated with a lack of net force (see a more detailed description of this below). Newton proposed that every object with mass has an innate inertia that functions as the fundamental

equilibrium "natural state" in place of the Aristotelian idea of the "natural state of rest". That is, the first law contradicts the intuitive Aristotelian belief that a net force is required to keep an object moving with constant velocity. By making rest physically indistinguishable from non-zero constant velocity, Newton's first law directly connects inertia with the concept of relative velocities. Specifically, in systems where objects are moving with different velocities, it is impossible to

determine which object is "in motion" and which object is "at rest". In other words, to phrase matters more technically, the laws of physics are the same in every inertial frame of reference, that is, in all frames related by a Galilean transformation.

For example, while traveling in a moving vehicle at a constant velocity, the laws of physics do not change from being at rest. A person can throw a ball straight up in the air and catch it as it falls down without worrying about applying a force in the direction the vehicle is moving. This is true even though another person who is observing the moving vehicle pass by also observes the ball follow a curving parabolic path in the same direction as the motion of the vehicle. It is the inertia of the ball associated with its constant velocity in the direction of the vehicle's motion that ensures the ball continues to move forward even as it is thrown up and falls back down. From the perspective of the person in the car, the vehicle and everything inside of it is at rest: It is the outside world that is moving with a constant speed in the opposite direction. Since there is no experiment that can distinguish whether it is the vehicle that is at rest or the outside world that is at rest, the two situations are considered to be physically indistinguishable. Inertia therefore applies equally well to constant velocity motion as it does to rest.

The concept of inertia can be further generalized to explain the tendency of objects to continue in many different forms of co(转 载于:wWw.SmHaIDA.cOM 海达 范文 网:关于牛顿的英语作文)nstant motion, even those that are not strictly constant velocity. The rotational inertia of planet Earth is what fixes the constancy of the length of a day and the length of a year. Albert Einstein extended the principle of inertia

further when he explained that reference frames subject to constant acceleration, such as those free-falling toward a gravitating object, were physically equivalent to inertial reference frames. This is why, for example, astronauts experience weightlessness when in free-fall orbit around the Earth, and why Newton's Laws of Motion are more easily

discernible in such environments. If an astronaut places an object with mass in mid-air next to himself, it will remain stationary with respect to the astronaut due to its inertia. This is the same thing that would occur if the astronaut and the object were in intergalactic space with no net force of gravity acting on their shared reference frame. This principle of equivalence was one of the foundational underpinnings for the development of the general theory of relativity.[11

Newton's second law

Main article:

A modern statement of Newton's second law is a vector differential equation:[12]

where is the momentum of the system, and is the net (vector sum) force. In equilibrium, there is zero net force by definition, but (balanced) forces may be present nevertheless. In contrast, the second law states an unbalanced force acting on an object will result in the object's momentum changing over time.[10]

By the definition of momentum

,

where m is the mass and is the velocity.

In a system of constant mass, the use of the constant factor rule in differentiation allows the mass to move outside the derivative

operator, and the equation becomes

.

By substituting the definition of acceleration, the algebraic version of Newton's second law

is derived:

It is sometimes called the "second most famous formula in physics".[13] Newton never explicitly stated the formula in the reduced form above.

Newton's second law asserts the direct proportionality of acceleration to force and the inverse proportionality of acceleration to mass. Accelerations can be defined through kinematic measurements. However, while kinematics are

well-described through reference frame analysis in advanced physics, there are still deep questions that remain as to what is the proper definition of mass. General relativity offers an equivalence between space-time and mass, but lacking a coherent theory of quantum gravity, it is unclear as to how or whether this connection is relevant on

microscales. With some justification, Newton's second law can be taken as a quantitative definition of mass by writing the law as an equality; the relative units of force and mass then are fixed.

Newton's second law can be used to measure the strength of forces. For instance, knowledge of the masses of planets along with the accelerations of their orbits allows

scientists to calculate the gravitational forces on

planets.

[edit] Newton's third law

Main article:

Newton's third law is a result of applying symmetry to situations where forces can be attributed to the presence of different objects. The Third Law means that all forces are interactions between different bodies,[16][17] and thus that there is no such thing as a unidirectional force or a force that acts on only one body. Whenever a first body exerts a force F on a second body, the second body exerts a force ?F on the first body. F and ?F are equal in magnitude and opposite in direction. This law is sometimes referred

to as the action-reaction law, with F called the "action" and ?F the "reaction". The action and the reaction are

simultaneous.

If object 1 and object 2 are considered to be in the same system, then the net force on the system due to the

interactions between objects 1 and 2 is zero since

This means that in a closed system of particles,

there are no internal forces that are unbalanced.

That is, the action-and-reaction force shared

between any two objects in a closed system will

not cause the center of mass of the system to

accelerate. The constituent objects only

accelerate with respect to each other, the system

itself remains unaccelerated. Alternatively, if

an external force acts on the system, then the

center of mass will experience an acceleration

proportional to the magnitude of the external

force divided by the mass of the system.[3]

Combining Newton's second and third laws, it is

possible to show that the linear momentum of a system is conserved

. Using

and integrating with respect to time, the

equation:

is obtained. For a system which includes

objects 1 and 2,

which is the conservation of linear

momentum.[18] Using the similar arguments, it is possible to generalizing this to a system of an arbitrary number of particles. This shows that exchanging momentum between constituent objects will not affect the net momentum of a system. In general, as long as all forces are due to the interaction of objects with mass, it is possible to define a system such that net momentum is never lost nor gained.[3]

篇四：牛顿第一定律英文版

Sir Isaac Newton first presented his three in the "Principia Mathematica Philosophiae Naturalis" in 1686. His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force resulting from unbalanced forces acting on an object (if all the external forces cancel each other out), then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. And if an

1

additional external force is applied, the velocity will change because of the force. The amount of the change in velocity is determined by Newton's of motion.

There are many excellent examples of Newton's first law involving aerodynamics. The motion of an when the pilot changes the throttle setting of the engine is described by the first law. The motion of a falling down through the atmosphere, or a being launched up into the atmosphere are both examples of Newton's first law. The motion of a when the wind changes can also be described by the first law. We have created separate pages which describe each of these examples in more detail to help you understand this important physical principle.
