Geometrically Add Subtract Vectors

When adding vectors graphically, the direction of the resultant vector is obtained by measuring

• the angle with the protractor
• the length of the vector once a scale is determined
• both of the above

To add vectors graphically one needs

• a value for the scale of the vectors being drawn.
• a ruler to measure the lengths of the vectors
• a protractor to measure the angles of the vectors
• all of the above

How should you add two vectors?

• Add them head to tail
• Add them tail to tail
• Add them with the addition key
• just add the length of each

When adding vectors graphically, the magnitude of the resultant vector is represented

• by the angle measured with the protractor
• the length of the vector after a scale is determined
• both of the above

What will be the resultant direction of a boat pointing due south while the river's current running due east?

• due south
• due east
• somewhere south of east
• none of these

When two vectors are added together, a _____________ can be drawn.

• vector
• resultant
• trajectory
• none of these 

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

The direction of the 10 N vector would be said to be

• North of West

• North of East

• East of North

• West of North
