Several force vectors all lie along the same straight line. What name is given to vectors like these?

1. Vectors that are parallel can be shifted so that they fall on a single line. 2. Vectors falling on the same line are called co-linear vectors. 3. A resultant is the single vector that replaces a whole group, so that word names the answer to the addition, not the group itself. 4. Components are the parts a single vector is broken into, which is the opposite operation. _Source: Siyavula Physical Sciences Grade 11 (Everything Science, CC BY 4.0), Chapter 1: Vectors in two dimensions_
