A scalar is a quantity that has only magnitude, such as length, mass, or temperature, while a vector is a quantity that has both magnitude and direction, such as velocity, force, or displacement. Scalars are added and subtracted by simple arithmetic, while vectors are added and subtracted using vector addition and subtraction rules. Scalars are represented by a single number, while vectors are represented by a magnitude and a direction.\n
