8-1 Geometric Vectors
• A vector is a quantity that has both _______________________ and
__________________________.
• A vector is represented geometrically by a _____________________________
_________________________________.
Magnitude: ____________________________________________________________
Initial: ________________________________________________________________
Terminal: ______________________________________________________________
• If a vector has its initial point at the ____________________, it is in
________________________ position.
• The direction of the vector is the ___________________ between the
_____________________________ and the vector.
• If both the initial point and the terminal point are at the origin, the vector is the
_______________________________.
• Two vectors are ___________________ ⇔ they have the same
_______________________ and _________________________.
Resultant: _______________________________________________________________
• Components: ______________________________________________________
example
Opposites: ______________________________________________________________
Scalar: _________________________________________________________________
• Multiplying a scalar and a vector changes the __________________ of the vector.
