    Hmm... This is a chp in a-maths... I appear to be having a mental block regarding the vector diagram thingy.... Help me plz ??? Thx.... :cry: :cry:

    To get any help you will need to post a problem.

    For those of you not in the know, A-maths stands for Additional Mathematics, which is an additional subject you can take in Singapore/Brunei if you're really good at maths. FateMaster is having trouble understanding vector diagrams constructed for relative velocity.

    FateMaster, you really need to be more specific in posting your problems. Understand that most people in PF (Physics Forums) are not from Singapore, or any South East Asian country. I'm from Brunei, though, so I perfectly understand your post. Unfortunately, we've yet to cover that topic in our A-Maths class.

    We might be using the same textbook. The textbook that I'm using is "New Additional Mathematics" by Ho Soo Thong and Khor Nyak Hiong. Is there something in the book that is badly explained? If so, let me know. I might be able to help.

    EDIT: I'm just curious. Are you in Secondary 3 or 4?

    x-----> x-----> x-----> x----->

    This shows a car (x) with a constant velocity using vector diagrams.

    x x-> x--> x---> x----> x---------->

    This shows a car (x) accelerating using a vector diagram.

    I hope this was helpful.

    PRodQuanta, FateMaster is talking about vector diagrams used in finding relative velocity. :smile:

    FateMaster, it may be helpful to look around in the homework forums. As I recall, there were quite a lot of problems being posted regarding this topic not too long ago.
