The law of vector addition that states that for more than two vectors, any order of grouping can be used as the answer will be the same.
6
New cards
Component Vectors
The projection of the vector on an axis.
7
New cards
Unit Vector
A vector that has a magnitude of exactly 1 and points in a particular direction. Its only purpose is to specify a direction.
