　　The following list defines all of the bold-faced words you encountered as you read this book.

 

　　C

 

　　Calorie

 

　　The amount of heat needed to raise the temperature of one gram of water by one degree Celsius. 1 cal = 4.19 J.

 

　　Celsius

 

　　A scale for measuring temperature, defined such that water freezes at 0oC and boils at 100oC. 0oC = 273 K.

 

　　Center of curvature

 

　　With spherical mirrors, the center of the sphere of which the mirror is a part. All of the normals pass through it.

 

　　Center of mass

 

　　Given the trajectory of an object or system, the center of mass is the point that has the same acceleration as the object or system as a whole would have if its mass were concentrated at that point. In terms of force, the center of mass is the point at which a given net

force acting on a system will produce the same acceleration as if the system’s mass were concentrated at that point.

 

　　Centripetal acceleration

 

　　The acceleration of a body experiencing uniform circular motion. This acceleration is always directed toward the center of the circle.

 

　　Centripetal force

 

　　The force necessary to maintain a body in uniform circular motion. This force is always directed radially toward the center of the circle.

 

　　Chain reaction

 

　　The particles and energy released by the fission or fusion of one atom may trigger the fission or fusion of further atoms. In a chain reaction, fission or fusion is rapidly transferred to a large number of atoms, releasing tremendous amounts of energy.

 

　　Charles’s Law

 

　　For a gas held at constant pressure, temperature and volume are directly proportional.

 

　　上面就是我们列举的SAT2物理常用术语，大家在备考SAT一定要对词汇方面有更多更加详细的准备。最后，提醒大家，在备考时一定要自己多查看一些资料以及相关讯息，这样考试的时候就能轻松应对。祝各位考生考出好成绩。
