I always seem to struggle in Mechanics 1 and cannot fully grasp the concepts, Core Math has never been a problem but it terrifies me how I am not able to understand Mechanics the way I want to. Any help would be greatly appreciated. Thanks
Not being able to understand the concepts or not being able to answer the questions? The former can't really be addressed with practice, such an approach would encourage you to memorise a method without really understanding it, which may cause you trouble in an exam, but can be addressed by people walking you through questions, say a teacher or a video. (examsolutions, etc.)

Why are you doing modules? The spec has changed - or aren't you in England?

Not being able to answer the questions actually. I can go back to the text book and learn a topic but when it comes to answering the questions, I always seem to get stuck.
That's the spec we're actually doing. We're doing our finals next year June.
I find vectors, statics of a particle, connected particles and particles on an inclined plane.
I thought you were in Year 12 because you mentioned C1 ... you should be on C3 now.
Most students find vectors harder so focus on the other topics first.
All three of the others need good daigrams - at least a third of the page and use a ruler.
You need to be clear if a system is in equlibrium or not.
Statics - system in equilibrium - resolve in two directions and/or take moments about a sensible point. Tell the examiner what you are doing ie moments @ A.
Connected particles - usually system moving so use F = ma on each string - be consistent about direction of accel. and you should get two simultaneous equations. If you add them, the T should be eliminated which enables you to get accel.
On an inclined plane - usually 'on point of slipping' so can resolve parallel and perpendicular to plane. If particle is moving then use F=ma parallel to plane [friction will be limiting] and resolve perpendicular as it is in equilibrium in that direction.

Actually in Year 13, we finished C3 about two weeks ago and have already started on C4.
How did you manage to answer the questions in Mechanics 1, was it continuous practice?
Thank you so much for the advice and the information. It's probably the best I've received these past 6 months. I hope you wouldn't mind me PM whenever I have a question and need an answer from someone else.

I teach maths so my A level was before modules!
I had a really good teacher and always enjoyed mechanics and enjoy teaching it now.
