In this lesson, you will about the difference between Vectors and Scalars and why these quantities are important in Physics, Math, and Engineering.

A Scalar is a quantity that has only magnitude. Examples are pressure, temperature, and time. A vector is a quantity that has both magnitude and a direction. Examples include velocity, force, and magnetic field.

We will use vector and scalar quantities extensively throughout this physics course and in engineering courses.
