of Vectors
A vector is a quantity that has both a
magnitude and a direction. Position is an
example of a vector quantity.
A scalar is a quantity with no direction.  The
mass of an object is an example of a scalar
quantity.

To add vectors graphically they must be placed “tip to
tail”.  The result (F
1
+ F
2
) points from the tail of the first
vector to the tip of the second vector.
This is sometimes called the resultant vector R
F
