Scalars and Vectors in Physics

This clip is just a few minutes of a multi-hour course.  
Master this subject with our full length step-by-step lessons!


Lesson Summary:
In this lesson, you'll learn about the very important topic of Scalars and Vectors in physics.  These are concepts that every student must master because all physics classes begin with a discussion of these topics.

Essentially, a scalar represents a quantity that has no direction associated with it, such as temperature.   A vector represents a quantity that has magnitude and a direction, such as the velocity of a train or rocket.

We explore these concepts in this lesson and give concrete examples so that the student has a good understanding of what a scalar is in comparison to a vector quantity.
