Intro to Geometric Vectors

A vector is a

• type of breakfast cereal that is quite tasty!

• sound effect used on the Simpsons

• quantity having magnitude and inflection.

• quantity having magnitude and direction.

• quantity having amplitude and ejection.

A Scalar is a

• quantity having only amplitude.

• quantity having only attitude.

• quantity having only direction.

• quantity having only magnitude.

• someone who can sing the song "Doh a dear, a female deer, Ray a drop of golden sun. Me a name....."

Equal vectors have the

• Same mother and father.

• Same magnitude and direction.

• Same argument and amplitude.

• Same attitude and inflection.

• Same latitude and longitude.

Opposite vectors have the

• The same direction but opposite magnitude.

• Same magnitude but opposite inflection.

• Same attitude but opposite direction.

• Same latitude but opposite longitude

• Same magnitude but opposite direction.

Geometric Vectors can be drawn using

• a white crayon and a parabola.

• a new device called a Vect-O-Grapher sold at WalMart.

• a directed line segment.

• a directed angle.

• a string, glue and some scotch tape.

Which of the following is the resultant of  $\overrightarrow{AB}+\overrightarrow{BC}$  ?

•  $\overrightarrow{AB}$  

•  $\overrightarrow{BC}$  

•  $\overrightarrow{AC}$  

•  $\overrightarrow{ABC}$  

•  $\overrightarrow{CBA}$  

Which of the following is the resultant of  $\overrightarrow{AB}-\overrightarrow{AC}$  ?

•  $\overrightarrow{CA}$  

•  $\overrightarrow{BC}$  

•  $\overrightarrow{AC}$  

•  $\overrightarrow{CB}$  

•  $\overrightarrow{BA}$  

1.  Vectors   $\overrightarrow{PQ}$  and   $\overrightarrow{RS}$  are:

• parallel vectors

• opposite vectors

• equivalent vectors

• none

Let $\overrightarrow{u}=\overrightarrow{MQ}$ and $\overrightarrow{v}=\overrightarrow{MN}$ . Write  $\overrightarrow{PQ}$  as terms of  $\overrightarrow{u}$ and  $\overrightarrow{v}$  

•  $\overrightarrow{u}+\overrightarrow{v}$  

•  $\overrightarrow{u}-\overrightarrow{v}$  

•  $\overrightarrow{u}$  

•  $-\overrightarrow{v}$  

Let $\overrightarrow{u}=\overrightarrow{MQ}$ and $\overrightarrow{v}=\overrightarrow{MN}$ . Write  $\overrightarrow{NQ}$  as terms of  $\overrightarrow{u}$ and  $\overrightarrow{v}$  

•  $\overrightarrow{u}+\overrightarrow{v}$  

•  $\overrightarrow{u}-\overrightarrow{v}$  

•  $\frac{1}{2}\left(\overrightarrow{u}-\overrightarrow{v}\right)$  

•  $\frac{1}{2}\left(\overrightarrow{u}+\overrightarrow{v}\right)$
