Hello there,
get the notion of position vectors for a particle, but why we use it instead of cartisean coordinates XYZ? What info does the vectors tell us that the cartisean coordinates doesn't tell us?
So if we say a point has coordinates x=2, y=3, z=5
We say its position vector is
r=i 2 + j 3 + k 5
What's the difference! I saw an article saying it's just another way of expressing the position
