What is a vector?

A vector is a mathematical object that has both magnitude and direction. Vectors are often represented as arrows in a coordinate system, with the length of the arrow representing the magnitude of the vector and the direction of the arrow indicating the direction of the vector. Vectors are commonly used in physics, engineering, and mathematics to represent quantities such as velocity, force, and displacement.

A vector is a mathematical entity that has both magnitude and direction. It is often represented as an arrow, where the length of the arrow represents the magnitude of the vector and the direction of the arrow represents the direction of the vector. Vectors are used in many areas of physics, engineering, and mathematics, such as describing the motion of objects, the forces acting on objects, and the flow of fluids.
