Pearson Edexcel IAL M2 Mechanics 2 Notes
Free Pearson Edexcel IAL M2 Mechanics 2 notes on plane motion, centres of mass, work, energy, collisions and the valid M1 + M2 route.
M2 Mechanics 2 is an IA2 applied unit in Pearson Edexcel International A Level Mathematics. It extends M1 Mechanics 1 into two-dimensional motion, centres of mass, energy, collisions and rigid-body statics. For the full Mathematics award, M2 is used in the M1 + M2 applied pair alongside compulsory P1 to P4.
Use this page as an independent revision note for the current Issue 3 specification. It is not Pearson's solution bank or a reproduced mark scheme. Your centre should confirm the units it will enter and cash in.
Official unit scope
- Kinematics of a particle moving in a plane.
- Centres of mass of discrete and composite bodies.
- Work, energy and power.
- Impulse, momentum and direct collisions.
- Further Newtonian modelling.
Where M2 fits
- Level: IA2 applied unit.
- Full IAL Mathematics route: M1 + M2.
- Official prerequisites: P1, P2, P3, P4 and M1 knowledge may be assumed.
- Revise first: M1 force diagrams, constant-acceleration motion, momentum, moments and a consistent sign convention.
The specification assumes prerequisite knowledge stated for the unit, so later-unit questions may combine earlier methods without re-teaching them. Treat the list above as an integrated toolkit. A question can begin in one topic and finish in another, such as using algebra to form a model, calculus to optimise it and a graph to interpret the result.
Core reasoning and methods
- Resolve plane motion into perpendicular components that share the same time.
- For composite centres of mass, treat removed pieces as negative mass only after defining a common origin.
