SpletA unit vector is a vector with a magnitude of one and no units. As such, a unit vector represents a pure direction. By convention a unit vector is indicated by a hat over a vector symbol. This may sound like a new concept, but it’s a simple one, directly related to the unit circle, the Pythagorean Theorem, and the definitions of sine and ... SpletWhat is a magnitude of a unit vector? Unit vectors are vectors whose magnitude is exactly 1 unit. They are very useful for different reasons. Specifically, the unit vectors [0,1] and [1,0] can form together any other vector. SpletVector quantities have a direction and a magnitude. However, sometimes one is interested in only the direction of the vector and not the magnitude. In such cases, for convenience, vectors are often "normalized" to be of unit length. These unit vectors are commonly used to indicate direction, with a scalar coefficient providing the magnitude.

SpletThe dot product of a vector with itself is the square of its magnitude. The dot product of two vectors is commutative; that is, the order of the vectors in the product does not matter. Multiplying a vector by a constant multiplies its dot product with any other vector by the same constant. The dot product of a vector with the zero vector is zero.
