Complete A-Level Maths Mechanics 2 (M2) Notes « StudyGuide.PK. A-Level Mechanics Maths Revision Tips. Mechanics is a subject that requires a lot of diagrams. Don't get lazy and cut corners. Learn the standard diagrams for a given topic so that you can draw them without having to think for too long. Use standard letters to simplify your work and include these in your diagrams. Forces: T for tension W for weight R for reaction (N for normal reaction or contact force can get confused with N for Newtons) F or Fr for friction or resistance to motion Fmax or Flim for limiting friction This will make your work much easier to follow, save you time and possibly less mistakes. Velocities and acceleration Label velocities with a single arrow above or below a particle and a double arrow to show acceleration.
Use u for initial velocities and v for final velocities where possible. Use subscripts for initial and final velocities of different particles A and B, such as uA, uB and vA, vB Common mistakes When reading a question, take care to see if the weight or the mass is given.

Notes fo mech on its way :) sorry, been rushing the notes for C2 and M1 here. time restraints. but will hopefully be able to neaten stuff up/improve and add more info some time soon. hope it helps nethertheless. haha I should write a textbook/revision guide... oh yeah, for mechanics, for every question, draw a clear but detailed labelled diagram. As you are modelling, people, cars etc. as a particle they are drawn as a box. Modelling means a simplified version of the mechanism, it includes only the important factors.
As you get further into mechanics, more factors are added (less and less moddeling assumptions are made) and everything gets more complicated, but a model is improved. Kinematics in 1D kinematics is the part of mechanics that deals with the motion of objects Velocity is a measurement that measures speed and direction. Displacement is another measurement that factors distance and direction. measured in m, but with direction written in afterwards too. kinematics in 2D Forces.
