Vectors like velocity and acceleration provide detailed spatial information beyond simple magnitudes. Represented as arrows with direction and length, vectors add and subtract geometrically, with components for each dimension. Understanding vector operations allows precise descriptions of position, displacement, and forces, laying a foundation for Newton’s Laws in later chapters.
