Master Vectors: Tips for Finding Relative Velocity & Adding/Subtracting Vectors

[Vals509]

Hi all

I have been studying vectors lately and am very confused as to how to :

• finding relative velocity
• adding and subtracting vectors

i am able to understand the basics of it but cannot get a hang of the harder questions. Does anyone know any website or example that can help explain the above 2 points properly!

Hyperphysics is a good site to use

There is some good youtube tutorials. I found very useful.. Just google it!

Surprisingly, SparkNotes has a pretty helpful outline. I think they also sell those folder-like study guide things with notes and all the formulas on them...you know, the things you can just stick in your binder? They have them for all sorts of subjects and are pretty helpful. I'm sure there's one for Physics or Vectors.

If you're looking for a higher level understanding of vectors and vector application. There is a book called Div, Grad, Curl. I can't remeber the author. There are multiple editions. Most larger libraries will carry a copy of at least one of the editions. The first chapter covers vector addition, subtraction, dot product, and cross product.

Here is the URL for the book "div, grad, curl" on amazon.com
