# M1 OCR (Not MEI) Exam - 9/06/2015 watch

This is probably the easiest maths module; as long as we don't get an awful paper like June14 we'll be fine.
Trust me, that was horrible

2i and 2ii. How do I know whether I do weight-tension or the other way round.

For Q2) i) You're going to be focusing on P as we don't have the weight of Q. So tension would be opposite to mg. As mg is pulling down on the string which creates an upward tension in the string. So if you do f = ma and do upwards as positive it would be T - mg = ma. But if you did downwards as positive it would me mg - T = m*-a (acceleration of p is upwards).

And the same for ii.

Well - which ever particle is lowering obviously has greater Weight. Therefore, the particle which moves towards the ground is T-W=ma.

If the particle is moving upwards, the Tension is greater, therefore the equation is W-T=ma.

Just think, what force is greater on either side? If W is greater, think -W. If it's T, think -T.

Does this help?
5. ugh im so nervous about this exam. ive put so much effort into it but a single error could cost me so many marks

mm I don't fully get it.

Check 6:31 on this video. What is the difference between what the question from the exam paper and what he is showing?

Edit: I think I may have interpreted the question wrong. I was looking at Q ffs. haha never mind.

He's showing the same thing

Oh okay. Glad you've got it!

Good Luck for the exam. I'm going to bed in a bit!

Hopefully we'll be fine. And try to remember the questions so we can have a unofficial mark scheme tomorrow! (no pressure though!)

Good Night.
9. Good luck for tomorrow everyone!

I think we should assign questions to make sure they're all remembered, theirs only 7 so we won't need more than 7 people and if we double up it only takes like 3

I'll remember questions 1 and 2
Alternatively some don just remembers them all or we just take faith in the idea we'll recall them all as a collective

Gotta get that ums tho what's it usually for 90-100?

I don't feel prepared haha! I think my problem is that sometimes I overthink the questions if that makes sense and then confuse myself with physics concepts. Plus I always make careless mistakes.
Since 2007, average for an A has been 56, 90 is 64, 100 is 70.75.

Hey what A-levels are you taking??
And what maths modules?

P.s. I'll try remember the answers too probably; if there's too much time left and I cba to check anymore I just start saving answers onto my calculator memory :P
