eeeeek i think i will crap this paper any tips? ive been doing physics in school for years and the style is just so different...
Yeah it is much different to anything else we've done isnt it , but just some general tips:

For every single question, draw a diagram. It helps SO much. So whether it's a simple momentum question, or a complex resolving forces up a plane question.

Make sure you have drawn all of the relevant forces, which may include mg, R, mgcosx, mgsinx, Rcox, Rsinx, Friction, Tension or a motive force.

For any question, write out the formula, for example, F = ma , or F = μR. You will get marks for this.

Direction is very important! For questions such as momentum and kinematics, always choose one direction as positive, and the opposite direction as negative.

When they say that tanθ = 3/4, then that means that cosθ = 4/5, and sinθ = 3/5 - no need to actually work out what θ is!

For moments questions, take your time - they're often worth quite a few marks, so no need to rush. Resolve both clockwise and anticlockwise about a point, and if necessary, about another point.

For vectors, all I can say is just know the formulae and know how to work out the magnitude (pythagoras), and know how to work out the time when a certain ship is due north of another ship - examples in the textbook

Do all of the mixed exercises and review exercises from the textbook.

Do as many past papers as you can.

Visit www.examsolutions.co.uk for any topics or past paper questions you're unsure about - it gives you step by step video worked solutions, a great resource!

If you're also taking c1 on the same day at the same time, try to practice doing a c1 paper, and immediately after, an m1 paper, under timed conditions, as that is how its going to be on the day

Good luck

I'm aiming for an A, over 90ums if I can manage it, would you recommend Soloman papers? or should I just complete all of the past papers?

Getting a good grade depends upon your understanding rather than the amount of past papers you do.

I got 100UMS in M1, i solved the whole book, did around 5 past papers(normally i do 1-2 past papers, but that time i had time so i did more).

I have never done solomons.

If you think you understand everything, then try one edexcel paper, and see if you can score full or close to full marks in it. If you get low marks, e.g. around 60-65 out of 75, then it means that you need to clear some of your concepts. Then go through the chapter again in the book, to make sure you understand everything.

Also do the review exercises in the book.
5. Re: Edexcel revision for Mechanics (M1) 16/05/12
I still struggle to get more than 65, still having the same problem with general understanding.
Like how do I know which way to draw the tension arrows.. I get confused with that.

And you can tell my understanding is poor because as soon as a question comes up that I haven't seen before I find it really tricky. Especially vectors.

7. Re: Edexcel revision for Mechanics (M1) 16/05/12
thanks a lot (: our physics teacher forces us into drawing diagrams and writing our formulas and approach clearly as well, so yeppp, i will listen to you both hahah i got 94/100 in my physics exam in school last year when we were being tested on mechanics. then this year we moved to electricity, magnetism and astronomy and i got 82/100, so i thought id be okay at mechanics but ive just realized the style is so different there are many easy marks, but often one or two questions that i cannot tackle at all pulls down my overall grade! ugh. okay thats irrelevant i know.

ive done C1 last time and got full marks, which is really awkward because ive applied for a resit in every unit ive done in january and now it shows up on my admission. i find it really stupid to go in and resit a unit in which i got full marks, but i also feel like an idiot if i take an admission form there for the second session when above that line it shows that ive signed up for the first..UGH! any suggestions?

8. Re: Edexcel revision for Mechanics (M1) 16/05/12
any got any tips regarding the vector chapter? I can do every single question in the past-papers but i always gets stuck on the vector questions!
soo yh Any advice or tips?

If you're just doing questions and hoping for the best then you don't understand the methods. Maybe look through the examples in your textbook?
heyy have you got any advice & tips when going for the vector questions? other then drawing diagrams that it is

No problem Lool erm quite a situation you've got yourself into. Erm why dont you just talk to your exams officer that you got full marks in c1 so you don't want to resit it. Or just go in at the first session, and do your m1 paper then, whilst everyone else is doing their c1 paper..

But whatever is the case, dont get to stressed about it lol

The best tip I can give you is go to www.examsolutions.co.uk and go through all of the vectors problems and videos. The guy on there can explain it a million times better than me so yeah
12. Re: Edexcel revision for Mechanics (M1) 16/05/12
i can take my m1 paper in the first session? hahah ill speak to those ppl..thanks !

Erm it really just depends on your school. And as they are both set for 9.00, yes, you should be able to take whichever you want first.

Not long left now, I really like this module; wish i could've done M2 instead of S2 .

I'm scoring 70-75/75 on papers, I just need to stop making silly mistakes like:

T-12+15 = T-3

i'm really struggling with vectors any tips?
could you please tell me the formulas used on all vector questions.
thanks.

Vectors arent as bad as you may think. Firstly, the formulas are :
v = u + at
r = r0 + vt

and for forces:

F-1 + F-2 +...+ F-n = F-Resultant

Here are some things you should know:
- If two ships or whatever are to collide then their equations of r = r0 + vt will be equal at some point in time
- If a ship is due east of another ship, then their j components will be equal
and vice versa for a ship due north of another ship

I cant really think of anything else at the moment, but if their are any particular questions that confuse you then let me know.

thanks, i don't get question 7c on this paper:
http://www.edexcel.com/migrationdocu...e_20110518.pdf
and when the questions says "....ship P is parallel to i" find vector in the form ai+bj how would i go about doing this?
thanks man.

If a ship is parallel to i, then its j component is equal to zero.

7c i - Like i mentioned above, if you want to find the time when a ship is due north of another ship then you need to equate the i components

So once you find the equations in terms of t(this is asked in 7b i and 7b ii), equate the i components and solve for t, which gives you the time when the ship is due north of the other

7c ii Here we need to realise that the vector of north-west is (-i + j),

So, what you need to do here is minus the equations that you found in terms of t.
As in rQ - rP(this is asked in part 7b iii, use that expression), and then once you've done that you must make the i component equal to the j component.

But remember to multiply the terms in the i component by -1, then equate them and solve for t.

Sorry if my explanation is not clear, but tell me what you dont understand from what ive said and i'll try to make it clearer.

I havent seen a question like 7c ii in all the papers ive done so far, first time seeing it for me.

There was one question in a fairly recent past paper (might actually have been june 2011) which asked to find the time when ship A was NORTH-EAST of ship B. What do you do there, completely perplexed

Or it may have been north-west, but still, same difference really
