I have a few doubts in Physics, mainly in Vectors and Scalars. I asked my professor for clarifications, but I ended up more confused.
So here you go:
(please note: this was my first "advanced" physics lecture, since i finished the 10th grade, so I may have some really basic doubts that do need clarifications)
1) How do I resolve vectors into X and Y components? (for applying component rule of addition)
2) What is a unit vector?
3)I did not understand this relation at all:
x = i ^ ( the "^" is meant to go above "i")
y = j^ (same as above)
z = k ^ (same as above)
Can you'll please help me out? If I dont understand these concepts, my next lecture is will be completely out of sorts as it is based on this lecture.
