Physics and maths mechanics - similar?

Is there anyone here who is either doing or has done the A2 physics course plus the mechanics modules in maths. This is because i do a2 physics and i have been looking at the mechanics specification and alot of the work is covered in physics. So i could do like 2 mechanics modules plus a pure module to gain an AS in further maths. It would mean i would have to teach it to myself with about 1 hours help a week from a teacher. But seeing as the physics and mechanics cover similar areas it shouldnt be too much extra work and it will help me to revise the physics. What does everyone think - especially those who have done physics and maths mechanics. How much extra work is involved?

Its aqa maths and physics. Also i just saw that there are loads of really good revision notes on here but are there any that are for maths aqa - most seem to be for edexcel.
Well, i'm doing AS physics and AS mechanics and I've found that they've both been relatively similar. The odd thing is different such as x (physics) and s (mechanics) for displacement, but I've found that physics has really been helpful, not sure about A2 though. I'll have to wait and see.

Most people take Edexcel Maths, I myself take OCR Physics but Spec B, most people take Spec A or Edexcel, not sure.

Mechanics in Maths is just calculation without understanding. Physics is more theory obviously. In mechanics u just do more deepened calculations thus more maths and makes it more fun and trivial.

I'd say mechanics in FM is much more interesting and not at all trivial. When you get to M3 it get's very interesting and calculus is involved in almost everything. This makes calculations and proofs much more realistic then using simple linear equations as in A-Level physics.
In physics you might be expected to calculate the period, given some data on the amplitude and velocity at a certain distance in hamonic motion. In M3 you might be expected to investigate the motion of a particle on an elastic string and prove the motion is simple harmonic about it's equilibrium point before going on to find algebraic expressions for the period and amplitude etc.

Im not sure that i was intending to do M3. I was going to do M1 M2 and P3 perhaps. But would it be possible to do M1 M2 and M3 for AS further maths - is this allowed?

You have to do P3 in standard maths and P4 in AS further maths. You could do some mechanics in your standard maths and more in further maths.

While both are based on the same underlying principles; the Mechanics course is much more Mathematical and much more detailed than the Physics one. This is especially true as you progress up the modular ladder. Although a firm foundation in Mechanics does make most of the Physics syllabus much easier and much more comprehensible. The Physics syllabus is very weak on Mechanics itself, and at this level, one would find it much easier to convert from the Mechanics course to the Physics course and not the other way round.

Your Mathematics AS-Level has to consist of two Pure modules and one Applied; hence you will only be able to do one Mechanics module.

The whole Mathematics A-Level has to consist of six modules. Three Pure and three applied. Where the standard modules, and hence the ones you have to do are P1, P2, P3, M1, S1 and then it is a choice from M2, S2, or in some cases D1.

The Further Mathematics A-Level has to consist of another six modules. P4, P5 OR P6 are compulsory.

Here is a list of the respective modules that I am taking or have already taken:

AS-Level: P1, P2, P3, M1, M2, S1

A2-Level: FP1 (P4), FP2 (P5), M3, M4, M5, D1,

Newton.

Im just doing Core 1 and Core 2 ( the new P1 and P2) with M1 in my A/S year and C3, C4 and M2 in my second year. Mechanics is exactly the smae as physics so far for me except that the mechanics questions are harder and more involved.

Eg. in physics I might be asked for the force required to move a 3 kg mass with an acceleration of 7 m/s/s on a smooth horizontal surface but in mechanics the mass might be on an incline of 30 degrees and there might be another force pushing the object horizontally into the slope.

At mechanics Im at an B/C grade , and for core a C/D, so for me the mech is easier, but like i said im only doing m1 now and m2 next year which is more than enough for me!
