AP物理课程B与C详细介绍

AP物理课程B与C详细介绍 AP物理考试往往放在AP考试的最后，那么大家对于这门理科课程了解多少呢？参加过AP考试的考生们对于AP物理课程各有不同的见解，没有参加过AP物理考试的新手们就一起来长长见识吧。 AP物理考试趋势分析如下：专家介绍，考生普遍认为AP物理课程比之前在学校所做的模拟考试以及自己复习时所用的真题难一些，但也并不出格。选择题的文字描述题稍微有点多，公式推导的比例也不小，导致阅读速度不够快或对公式不够熟悉的同学在后期时间非常紧，精神上也比较疲惫。而大题只有6道，而非往年的7道。前面运动学、力学的部分大家认为中规中矩，基本能答出，有匀速圆周运动相关，有弹簧问题。其中两问是关于一根弹簧挂着小球做圆周运动的实验，相当于圆周运动（向心力）和弹簧问题的综合，有简谐振动中周期-频率的问题。电磁题被大多数考生称为难点，但根据大家的描述，笔者认为其场景也并不算罕见：首先有电路，然后其中的平行板电容器的板间又被施加垂直于电场的磁场，一个电子先通过这样一个区域，之后再通过一个只有磁场的区域。这样的题目，这时应该联系电场力和磁场力的受力分析来解答。热力学方面就是非常常见的考点：热力学第一定律、W = -PΔV和PV图像的应用。流体力学考了海水中有气泡的情况，也就是浮力题。而本次考试中光学的份额非常小，仅在浮力题中占一两小问，让学生画光线经过水中气泡之后的光路图以及全反射问题，也不算难，只要熟悉光学定律和作图即可。原子核物理的部分一如既往地简单，属于拿分部分。大致就是求能量E = hf、电子能级跃迁等等，学生经过一些复习之后照着公式列表都可以顺利做出来，不少学生是优先做完

解读美国AP物理课程

解读美国A P物理考试 A P是A d v a n c e d P l a c e m e n t的缩写，中文一般翻译为美国大学预修课程，是由美国大学理事会（T h e C o l l e g e B o a r d）提供的在高中授课的大学课程。美国高中生可以选修这些课程，在完成课业后参加A P考试，得到一定的成绩后可以获得大学学分。美国高中A P课程有22个门类、37个学科，已在美国 15000多所高中里普遍开设。它可以使高中学生提前接触大学课程，避免了高中和大学初级阶段课程的重复。 A P考试的成绩使用5分制，考生可以获得1，2，3，4或者5分。一般三分或三分以上的成绩可以在大学换取学分，但也

有很多特殊的例子，某些名牌大学接受的标准在4分以上或者5分，有些大学则不接受A P成绩。目前，已有40多个国家的近3600所大学承认A P学分为其入学参考标准和该项考试为考生增添的大学学分，其中包括哈佛、耶鲁、牛津、剑桥、帝国理工等世界名牌大学。 A P考试每年5月举行，目前已经在全球80个国家开设。 A P成绩已成为美国大学重要录取依据。根据美国大学升学顾问委员会在全美范围内所作的调查，由于美国大学已经普遍把学生在A P考试中的表现作为衡量其是否能够胜任大学学习的依据，因此A P考试成绩已经成为众多大学录取考虑因素中最为重要的依据之一。考试通过的A P课程可以折抵大学学分，减免大学课程，帮助学生缩短大学学时、跳级，更可节省高昂大学学费。更重要的是，据统计，拥有优异A P考试成绩的高中生在未来的大学学习有更佳出色的表现和发展，美国各大学已将A P成绩看作衡量学生学习和研究能力以及应付高难度大学课程能力的重要指标。参加A P考试科目多、考分高的学生被美国名校另眼相看。英国、加拿大、澳大利亚等国也将此作为发放奖学金的主要条件之一。今天我们来介绍一下A P考试中的物理：

AP物理C力学必备知识梳理复习课程

AP物理C力学对于目标工科的留学党来讲，AP物理C几乎是必学科目。当然还有纯粹对AP物理C是爱好的小伙伴们，今天小编为小伙伴们梳理了AP 物理C力学的考点，内容很全，尤其适合考前梳理，一起来看一下吧。 Newtonian Mechanics 牛顿力学、占整个PhysicsC力学考试的100% Kinematics运动学占18% “矢量（vectors）的概念既有大小，又有方向；矢量代数（vector algebra）.矢量和的三角形法则是必须熟练掌握的，最简单的记忆方法就是花萌萌面对两段直的折线路径（对应两段位移矢量之和），她会选择直接连接出发点和终点的直线捷径（等效的对应两个位移矢量和），这样构成了一个矢量和三角形。 “矢量的点乘A B=ABcosΘ（加重符号都表示矢量）和叉乘（大小）／A×B／=／ABsinΘ／（叉乘结果是矢量，方向为从A绕到B的右手螺旋系大拇指方向），Θ为矢量A和B的夹角。矢量的加减，点乘和叉乘，是矢量分析的基础，是我们学习AP物理C的基本数学框架一定要熟练掌握。矢量在直角坐标系中的分量（components of vectors,coordinate systems）,特别强调的是物理上只会用“右手系”，也就是从X轴到Y轴的右手螺旋拇指指向Z轴，这个和叉乘的定义是一样的，好记！有了ta，大家在学电磁学的时候就不用左右手的拧麻花了。 AP物理C还需要掌握柱坐标和球坐标，这在需要柱对称和球对称的积分问

题时，就很有用了。 “运动学中要用到的三大矢量位移、速度和加速度（displacement,velocity and acceleration)，特别要注意别把距离（或者叫路程distance），速率（speed）和前面的概念搞混了，后两个概念是标量，只有在一些特殊情况下才和对应矢量的模（大小）相等。 “一维运动（Motion in one dimension）一维运动的矢量性就记住有正负的方向就行，对于一维匀加速直线运动，务必掌握其最重要的三个方程：第一,求速度的公式Vf=V i+at角标i（initial）和f（final）总是代表初和末，这个公式只要从匀加速度等于平均加速度的定义就可以得到：第二,求位移的公式ΔX=V it+1/2at2这个公式可以理解为保持初速度的匀速运动位移和初速为零的匀加速运动位移之和第三,2aΔX=Vf2-Vi2公式是把前面两个公式消去变量⊿t，得：更方便的记忆方法是公式左边用牛顿第二定律F=ma，变成外力做功的形式：F⊿x,左边多出来的2/m转到右边，右边就正好得到物体动能的变化。二维运动第一,抛射体运动（Motion in two dimensions,including projectile motion），抛射体运动由于可以在直角坐标系中进行矢量分解，所以也就是水平方向的匀速运动和垂直方向的匀加（减）速运动（注意Y轴向上，所以重力加速度在公式中是负的：-g）第二,相对运动，关键的公式是：物体相对于地的（earth）速度等于相对于地参考系（reference）的速度加上物体相对于参考系（relative）的速度，特
