  M1是A-level數(shù)學的考試內(nèi)容,主要涉及的知識點為力與運動、功與能,以及涉及到數(shù)學方法和物理概念相結合的微分和積分知識。今天,A+國際教育小編就為大家總結了alevel數(shù)學M1考點,來看看你是不是已經(jīng)完全掌握了。

Alevel數(shù)學m1考點


  M1的考點可以分為以下幾個大點:


  1.Mathematical models in mechanics(力學中的數(shù)學模型)


  2.vectors(向量)


  3.kinematics of a particle moving in a straight line(運動學)


  4.dynamics of a particle moving in a straight line(動力學)


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


  5個考點中唯一不會單獨出題的點


  Mathematical models in mechanics(力學中的數(shù)學模型)


  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考點比較容易出現(xiàn)的題型:


  1.在航海問題中用向量表示及計算速度,位移,加速度等向量。


  2.求某一物體的方位(bearing),應當以正北方為基準,順時針旋轉所得的角度。


  3.向量在運動學和動力學的綜合題,應特別注意的是如物體運動方向平行i軸,則物體速度j前面的系數(shù)為0.如平行j軸運動,則i的系數(shù)為0.


  kinematics of a particle moving in a straight line;(物體運動在直線上的運動學)


  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.


  在這一考點中需要注意的點有:1.5個運動公式的靈活運用;2.計算前單位統(tǒng)一轉換成國際單位;3.勻減速運動,自由落體運動中正方向的選??;4.斜面上的斷線問題。


  dynamics of a particle moving in a straight line(動力學)


  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.


  在這個考點里,考試中最基礎的題型為力的分解,易錯點位摩擦力類型及方向的判斷,整體法及部分法的應用。動量及沖量計算中正方向的選取。


  statics of a particle;moments.(靜力學,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,考試中不會單獨出題,而是在其他知識點中能應用這些模型的假設就可以)。


  以上就是A+小編關于Alevel數(shù)學M1考點的總結,縱觀A-level中的M1歷年試題,試題難度比較平穩(wěn),主要考察學生應用數(shù)學工具解決物理力學問題,考查的知識點分布比較固定,題目難度相對于數(shù)學中的Paper3(純數(shù)3)和Paper6(統(tǒng)計1)不難,主要知識點是把AS物理中的力與運動部分以及純數(shù)中的簡單微積分知識相結合。同學們?nèi)绻贏level數(shù)學學習和備考中有什么問題,歡迎隨時咨詢我們喲!
