Alevel數(shù)學(xué)M1考點(diǎn)解析,你要掌握哪些知識(shí)點(diǎn)?

 

  M1是A-level數(shù)學(xué)的考試內(nèi)容,主要涉及的知識(shí)點(diǎn)為力與運(yùn)動(dòng)、功與能,以及涉及到數(shù)學(xué)方法和物理概念相結(jié)合的微分和積分知識(shí)。今天,A+國(guó)際教育小編就為大家總結(jié)了alevel數(shù)學(xué)M1考點(diǎn),來看看你是不是已經(jīng)完全掌握了。

Alevel數(shù)學(xué)m1考點(diǎn)


  M1的考點(diǎn)可以分為以下幾個(gè)大點(diǎn):


  1.Mathematical models in mechanics(力學(xué)中的數(shù)學(xué)模型)


  2.vectors(向量)


  3.kinematics of a particle moving in a straight line(運(yùn)動(dòng)學(xué))


  4.dynamics of a particle moving in a straight line(動(dòng)力學(xué))


  5.statics of a particle;moments(靜力學(xué),力矩)


  5個(gè)考點(diǎn)中唯一不會(huì)單獨(dú)出題的點(diǎn)


  Mathematical models in mechanics(力學(xué)中的數(shù)學(xué)模型)


  Students should be familiar with the terms:particle,lamina,rigid body,rod(light,uniform,non-uniform),inextensible string,smooth and rough surface,light smooth pulley,bead,wire,peg.


  vectors(向量)


  1.Magnitude and direction of a vector.


  2.Resultant of vectors may also be required.


  Students may be required to resolve a vector into two components or use a vector diagram.Questions may be set involving the unit vectors i and j.Application of vectors to displacements,velocities,accelerations and forces in a plane.


  A-Level M1考點(diǎn)比較容易出現(xiàn)的題型:


  1.在航海問題中用向量表示及計(jì)算速度,位移,加速度等向量。


  2.求某一物體的方位(bearing),應(yīng)當(dāng)以正北方為基準(zhǔn),順時(shí)針旋轉(zhuǎn)所得的角度。


  3.向量在運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)的綜合題,應(yīng)特別注意的是如物體運(yùn)動(dòng)方向平行i軸,則物體速度j前面的系數(shù)為0.如平行j軸運(yùn)動(dòng),則i的系數(shù)為0.


  kinematics of a particle moving in a straight line;(物體運(yùn)動(dòng)在直線上的運(yùn)動(dòng)學(xué))


  Motion in a straight line with constant acceleration.Graphical solutions may be required,including displacement-time,velocity-time,speed-time and acceleration-time graphs.Knowledge and use of formulae for constant acceleration will be required.


  在這一考點(diǎn)中需要注意的點(diǎn)有:1.5個(gè)運(yùn)動(dòng)公式的靈活運(yùn)用;2.計(jì)算前單位統(tǒng)一轉(zhuǎn)換成國(guó)際單位;3.勻減速運(yùn)動(dòng),自由落體運(yùn)動(dòng)中正方向的選?。?.斜面上的斷線問題。


  dynamics of a particle moving in a straight line(動(dòng)力學(xué))


  1.The concept of a force.


  2.Newton’s laws of motion.Simple problems involving constant acceleration in scalar form or as a vector of the form ai+bj.


  3.Simple applications including the motion of two connected particles.


  4.Momentum and impulse.The impulse-momentum principle.The principle of conservation of momentum applied to two particles colliding directly.


  5.Coefficient of friction.


  在這個(gè)考點(diǎn)里,考試中最基礎(chǔ)的題型為力的分解,易錯(cuò)點(diǎn)位摩擦力類型及方向的判斷,整體法及部分法的應(yīng)用。動(dòng)量及沖量計(jì)算中正方向的選取。


  statics of a particle;moments.(靜力學(xué),力矩)


  Forces treated as vectors.Resolution of forces.Equilibrium of a particle under coplanar forces.Weight,normal reaction,tension and thrust,friction.Only simple cases of the application of the conditions for equilibrium to uncomplicated systems will be required.Coefficient of friction.Moment of a force.


  考點(diǎn)主要考察


  1、物體在平衡狀態(tài)中力的分解,極限平衡狀態(tài)中摩擦力方向的判斷。


  2、力矩的理解,共面力矩和的計(jì)算,平衡狀態(tài)物體力矩的分析。


 ?。ㄟ@一些模型的概念理解就可以,考試中不會(huì)單獨(dú)出題,而是在其他知識(shí)點(diǎn)中能應(yīng)用這些模型的假設(shè)就可以)。


  以上就是A+小編關(guān)于Alevel數(shù)學(xué)M1考點(diǎn)的總結(jié),縱觀A-level中的M1歷年試題,試題難度比較平穩(wěn),主要考察學(xué)生應(yīng)用數(shù)學(xué)工具解決物理力學(xué)問題,考查的知識(shí)點(diǎn)分布比較固定,題目難度相對(duì)于數(shù)學(xué)中的Paper3(純數(shù)3)和Paper6(統(tǒng)計(jì)1)不難,主要知識(shí)點(diǎn)是把AS物理中的力與運(yùn)動(dòng)部分以及純數(shù)中的簡(jiǎn)單微積分知識(shí)相結(jié)合。同學(xué)們?nèi)绻贏level數(shù)學(xué)學(xué)習(xí)和備考中有什么問題,歡迎隨時(shí)咨詢我們喲!
