Help with Relative Velocity Maths Vector Diagram

Click For Summary

Discussion Overview

The discussion revolves around understanding vector diagrams in the context of relative velocity, particularly within the framework of Additional Mathematics (A-maths) as taught in Singapore and Brunei. Participants express varying levels of familiarity with the topic and seek assistance in grasping the foundational concepts.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • FateMaster expresses difficulty with vector diagrams related to relative velocity and requests help with the basics.
  • Some participants suggest that more specific problems need to be posted for effective assistance.
  • One participant mentions that they are also studying A-maths and inquires about the textbook used, indicating a shared context.
  • Another participant provides examples of vector diagrams for constant velocity and acceleration, although it is unclear how these relate to relative velocity specifically.
  • There is a suggestion to explore homework forums for previously posted problems on the topic of relative velocity.
  • Participants acknowledge a misunderstanding regarding the specific focus of FateMaster's question.

Areas of Agreement / Disagreement

Participants generally agree that more specificity is needed in the questions posed. However, there is no consensus on the best approach to explaining vector diagrams for relative velocity, and the discussion remains unresolved regarding the foundational concepts.

Contextual Notes

Some participants note that they may not have covered the topic in their classes yet, indicating potential limitations in their ability to provide assistance. There is also mention of a specific textbook that may have unclear explanations, but this remains unverified.

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

To get any help you will need to post a problem.
 
Realli ? Hmm... Well... We can start with the basics... i dun even understand the basics of this topic... So... i guess you can start from there... ^^

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.
 
AH, i see. Misunderstanding.
