What Is The Difference Between Scalar And Vector. Scalar and vector quantities are the two mathematical quantities that explain the motion of a body. For a common person, the two terms are the same, but there is a huge difference between them in physics.
Let us now discuss what is the difference between scalar and vector. The vector is a quantity that has both real-valued magnitude and direction. A scalar quantity has magnitude but no direction.
A scalar quantity is a one dimensional measurement of a quantity, like temperature, or mass.

Scalars are quantities that have magnitude only; they are independent of direction. A scalar is a physical quantity having a magnitude but no direction. An arrow is used to indicate vector quantity, placed over or next to the symbol that denotes vector.
