 **Scalars:** Quantities that can be represented by a single number. Typical examples include mass, volume, density, and speed.

 **Vectors** Quantities than have both a magnitude and direction. Typical examples include displacement, velocity, momentum, and force.
-Vectors are often represented with arrows. The end with the triangle is the "tip" or "head". The other end is called the "tail". The tail of a vector can be located anywhere; it is the difference between the tip and the tail that defines the vector itself.
+Vectors are often represented with arrows. The end with the triangle is the "tip" or "head". The other end is called the "tail". The tail of a vector can be located anywhere; it is the difference between the tip and the tail that defines the vector itself. To the right is an example of a typical representation of a vector with the tip and tail labeled.
