Only if vectors are involved.


Am I right in saying that if it says find the magnitude in a question that isn't about vectors, do you find the size/value of whatever it is that you've been asked to find the magnitude of?

I'll have a go at them, thanks! Any others you recommend?


Trying Jan 2014 IAL at the moment, and it definitely isnt easy so that might be a shout.

Yes.


when you say magnitude cant i use F=MA if the weight is given
and is M the weight or mass?

Really confused about how to go about part 3(b)? Anyone?

What are you talking about.

Take moments about D making sure to remember that the distance will be the length from one corner to the other corner (use Pythagoras to find the length of the diagonal).
Well, I'm in quarantine tomorrow, so much fun...

anyone got predilections of what is likely to come up ?


i would always expect a big pulley question. First question is usually collissions.
And you would expect either one big vector question or a small vector question and a medium vector question
how long does it usually take for you to complete the M1 exam, do you have a lot of spare time to check your answers?

i am not sure which paper it was but it asked to find the resultant magnitude i think, mass was given and above that acceleration is supposed to be found
and F=MA was used

About 30-40 minutes iirc.


Can someone explain how the answer to part a) is (6i + 8j)?

I would prefer no vectors but I don't think that's gonna happen XD

You have to draw a diagram and stuff its complex check mark scheme

I can find the moments for the others but i don't know what to do with X. i worked out that its length is 2root2 but then how do i find its moment, multiply by 2 to get the distance of X from D? i.e. my question is how to get the moment of X?

I've checked the mark scheme and I can't really make sense of it.

For resolving forces questions is it ok to annotate the diagram? Or do you have to draw a new one out? Basically will you lose marks if you do your working on the diagram given?
