sat考试物理必背的高频词汇1
Latent heat of fusion
The amount of heat necessary to transform a solid at a given temperature into a liquid of the same temperature, or the amount of heat needed to be removed from a liquid of a given temperature to transform it into a solid of the same temperature.
Latent heat of sublimation
The amount of heat necessary for a material undergoing sublimation to make a phase change from gas to solid or solid to gas, without a change in temperature.
Latent heat of transformation
The amount heat necessary to cause a substance to undergo a phase transition.
Latent heat of vaporization
The amount of heat necessary to transform a liquid at a given temperature into a gas of the same temperature, or the amount of heat needed to be taken away from a gas of a given temperature to transform it into a liquid of the same temperature.
Law of conservation of energy
Energy cannot be made or destroyed; energy can only be changed from one place to another or from one form to another.
Law of reflection
For a reflected light ray, . In other words, a ray of light reflects of a surface in the same plane as the incident ray and the normal, and at an angle to the normal that is equal to the angle between the incident ray and the normal.
Legs
The two shorter sides of a right triangle that meet at the right angle.
Lenz’s Law
States that the current induced in a circuit by a change in magnetic flux is in the direction that will oppose that change in flux. Using the right-hand rule, point your thumb in the opposite direction of the change in magnetic flux. The direction your fingers curl into a fist indicates the direction of the current.
Longitudinal waves
Waves that oscillate in the same direction as the propagation of the wave. Sound is carried by longitudinal waves, since the air molecules move back and forth in the same direction the sound travels.
Loudness
The square of the amplitude of a sound wave is called the sound’s loudness, or volume.

Impulse
A vector quantity defined as the product of the force acting on a body multiplied by the time interval over which the force is exerted.
Incident ray
When dealing with reflection or refraction, the incident ray is the ray of light before it strikes the reflecting or refracting surface.
Inclined plane
A wedge or a slide. The dynamics of objects sliding down inclined planes is a popular topic on SAT II Physics.
Index of refraction
The index of refraction n = c/v of a substance characterizes the speed of light in that substance, v. It also characterizes, by way of Snell"s Law, the angle at which light refracts in that substance.
Induced current
The current induced in a circuit by a change in magnetic flux.
Inelastic collision
A collision in which momentum is conserved but kinetic energy is not.
Inertia
The tendency of an object to remain at a constant velocity, or its resistance to being accelerated. Newton’s First Law is alternatively called the Law of Inertia because it describes this tendency.
Inertial reference frame
A reference frame in which Newton’s First Law is true. Two inertial reference frames move at a constant velocity relative to one another. According to the first postulate of Einstein’s theory of special relativity, the laws of physics are the same in all inertial reference frames.
Instantaneous velocity
The velocity at any given instant in time. To be contrasted with average velocity, which is a measure of the change in displacement over a given time interval.
Internal energy
The energy stored in a thermodynamic system.
Inversely proportional
Two quantities are inversely proportional if an increase in one results in a proportional decrease in the other, and a decrease in one results in a proportional increase in the other. In a formula defining a certain quantity, those quantities to which it"s inversely proportional will appear in the denominator.
Isolated system
A system that no external net force acts upon. Objects within the system may exert forces upon one another, but they cannot receive any impulse from outside forces. Momentum is conserved in isolated systems.
Isotope
Atoms of the same element may have different numbers of neutrons and therefore different masses. Atoms of the same element but with different numbers of neutrons are called isotopes of the same element.

gre考试必须掌握的一些高频词汇2
1.当你决定了要考GRE和准备出国这条路的时候，我希望你已经考虑清楚了。因为这条路注定难走，这段时间注定难熬。
Be a god* grown up man
2. 这几个月你会为此放弃很多事情：睡懒觉，看电影，看美剧，甚至包括感情，情绪。
Be discipline
单词作为GRE考试的一大拦路虎成了多少人不可逾越的障碍。请大家记得以下几个原则
1.背红宝书和新要你命三千的单词是远远不够的
请尽量结合文章看单词，这样你才知道单词的connotation,这样你才知道单词的用法
2. 请准备好小本子随时记下自己不认识的单词
红宝书和新要你命三千那两本单词书没有你想象的那么神奇，无法涵盖100%的单词量。请大量阅读。 Read a lot, read dense.
3. 请反复不断地背单词
这个过程应该是从第一天持续到最后一天的
4. 背单词只有认识和不认识
请不要相信自己所谓的”好像认识”，不能100%准确讲出意思的单词就是不认识。不要相信考场上有奇迹：可以让你根据上下文推测出那些模糊的意思。 torpid, torpor, torrid, turgid, turbid 你认识就是认识，学术的世界里没有好像，没有差不多
5. 有精力的话请看1-2本英文单词书
Barron 1100 Words You Need to Know和 Verbal Advantage是首推的
6. 请与好书为伴，勤翻阅各类报刊杂志
The New Yorker, The Economist, The Browser, Aldaily都应该成为你的必读项目
Freud, Chaucer, Hegel, John Locke etc都应该成为你的好基友
