Vectors

Which statement describes a vector?

• It has magnitude but no direction
• It has direction but no magnitude
• It has both direction and magnitude
• It has constant magnitude but no
   direction

Vector is a quantity with:

• magnitude and direction

• magnitude

• direction

• none of the above

• ab

• b + a

• 3a + b

• 4a

What is the magnitude of the resultant vector, r?

• 3

• 4

• 5

• 7

A vector includes ______ and ________.

• direction, magnitude

• magnitude, units

• direction, units

• scalars, scalars

If two vectors have the same direction then they are

 $\overrightarrow{AB}=\overrightarrow{BC}$  Implies B is the ....... of AB

Expand into single vector: $\overrightarrow{BJ}-\overrightarrow{LM}+\overrightarrow{JM}-\overrightarrow{BA}$  

 $\overrightarrow{AB}-\overrightarrow{CB}-\overrightarrow{DC}-\overrightarrow{ED}$  Write this as one vector

 $\overrightarrow{BA}+\overrightarrow{BC}=\overrightarrow{BD}$  Then D is the fourth vertex of a parallelogram :

• ABCD

• BCAD

• CADB

• None of the above
