Definition of a Vector
Point of Application
- A vector is a visual representation of a force.
The force needs to have a point on which it is
being applied.
Direction
- A vector must have a specific direction defined
by either coordinates, or degrees.
Magnitude
- The vector must have length, or magnitude.
Magnitude defines the amount of force applied
to the point of application.

Addition
Tip-to-tail
- Adding by connecting the tip of vector
A to the tail of vector B. Then draw a
new vector from the tail of vector A to
the tip of vector B, and that is the sum of
the two vectors.

Multiplication
Dot Product
- Multiply the corresponding components
of vectors A and B. For example vector A
= [ 3,2 ], vector B = [ 4,7 ].
A • B = (3 x 4) + (2 x 7) = 26
Cross Product
- Set up vectors in cross product form.

Unit Vector
A unit vector is denoted as a “hatted”
letter. An example, â.
Converting using the norm
- To convert a vector into a unit vector,
divide by the normal vector.
= normal vector
= unit vector
Home
Zero Vector
Has no magnitude
Has no direction
All components are equal to zero
Home
Theorems
Two vectors are equivalent if they have
the same direction and magnitude.
If a vector, denoted by A, has the same
magnitude but opposite direction as
vector B, then vector B can be shown as
-A.
Home
Laws
Addition
- Commutative law: A+B = B+A
- Associative law: A+(B+C) = (A+B)+C
Multiplication
- mA = Am
- (m+n)A = mA + nA
m and n are different scalar quantities

Definition of a Vector
Point of Application
- A vector is a visual representation of a force.
The force needs to have a point on which it is
being applied.
Direction
- A vector must have a specific direction defined
by either coordinates, or degrees.
Magnitude
- The vector must have length, or magnitude.
Magnitude defines the amount of force applied
to the point of application.

Addition
Tip-to-tail
- Adding by connecting the tip of vector
A to the tail of vector B. Then draw a
new vector from the tail of vector A to
the tip of vector B, and that is the sum of
the two vectors.

Dot Product
- Multiply the corresponding components
