What is the term for vectors that are all in the same plane?

The term for vectors that are all in the same plane is co-planar vectors. This refers to a specific geometric relationship where multiple vectors lie within the same two-dimensional plane. Understanding co-planar vectors is important in physics and engineering as it allows for the analysis of forces, velocities, and other vector quantities acting in the same environment without needing to consider any potential three-dimensional aspects. This concept simplifies calculations and graphical representations, making it easier to visualize the interactions between the vectors involved.

Concurrent vectors, on the other hand, refer to vectors that all meet at a single point but do not necessarily lie in the same plane. Resultant vectors are the vector sums of two or more vectors, while collinear vectors are vectors that lie along the same straight line, which may or may not be in the same plane. Thus, co-planar is the appropriate term for describing vectors confined to one plane.
