J和K开头的SAT2物理专业词汇解析

下面为大家整理的是关于SAT2物理专业词汇中以字母J和K开头的单词，后面附有详细的英文解析，没有汉语含义的介绍。大家在备考SAT2物理考试的时候，掌握这些专业词汇是重中之重，下面就一起来看看这些词汇的详细内容吧。
　　Joule
　　The joule (J) is the unit of work and energy. A joule is 1 N · m or 1 kg · m2/s2.
　　Kelvin
　　A scale for measuring temperature, defined such that 0K is the lowest theoretical temperature a material can have. 273K = 0?C.
　　Kepler’s First Law
　　The path of each planet around the sun is an ellipse with the sun at one focus.
　　Kepler’s Second Law
　　If a line is drawn from the sun to the planet, then the area swept out by this line in a given time interval is constant.
　　Kepler’s Third Law
　　Given the period, T, and semimajor axis, a, of a planet’s orbit, the ratio is the same for every planet.
　　Kinematic equations
　　The five equations used to solve problems in kinematics in one dimension with uniform acceleration.
　　Kinematics
　　Kinematics is the study and deｓｃｒｉｐｔion of the motion of objects.
　　Kinetic energy
　　Energy associated with the state of motion. The translational kinetic energy of an object is given by the equation .
　　Kinetic friction
　　The force between two surfaces moving relative to one another. The frictional force is parallel to the plane of contact between the two objects and in the opposite direction of the sliding object’s motion.
　　Kinetic theory of gases
　　A rough approximation of how gases work, that is quite accurate in everyday conditions. According to the kinetic theory, gases are made up of tiny, round molecules that move about in accordance with Newton’s Laws, and collide with one another and other objects elastically. We can derive the ideal gas law from the kinetic theory.
　　以上就是以字母J和K开头的SAT2物理专业词汇的全部内容，不是很多。专家提醒考生在记忆SAT2物理词汇的时候，一定要注意和做题结合起来，这样才能取得更好的记忆效果，也能取得更好的应用效果。
