myusernameis said:Ok, so a vector is direction and magnitude, and by finding the unit vector we divide the vector by the length of that vector, |v|
does that mean we get the direction of the vector?

A vector is a mathematical object that has both magnitude (size) and direction. It is typically represented by an arrow, where the length of the arrow represents the magnitude and the direction of the arrow represents the direction.
To find the direction of a vector, you need to calculate its unit vector. This can be done by dividing the vector by its magnitude, resulting in a vector with a magnitude of 1. The direction of the unit vector is the same as the original vector.
A unit vector is a vector with a magnitude of 1. It is used to indicate the direction of a vector, as its direction is the same as the original vector. It is often denoted by a hat symbol (^) on top of the vector symbol.
Finding the direction of a vector is important because it allows us to understand the direction in which a quantity is moving or acting. This is particularly useful in fields such as physics and engineering, where vectors are used to represent forces, velocities, and other physical quantities.
To calculate the unit vector, divide the vector by its magnitude. The resulting vector will have a magnitude of 1 and the same direction as the original vector. This can be written as u = v / |v|, where u is the unit vector and v is the original vector.
