👉 Orthonectida is a type of mathematical model used in physics and engineering to describe the relationship between two vectors. It describes how these vectors are related, with each vector being perpendicular to the other. In other words, it represents the direction and magnitude of the components of one vector that are orthogonal to another. Orthonectida models are often used in problems involving forces acting on a rigid body or in determining the motion of objects under constant acceleration.
