graphical vectors

A resultant vector is

• equal to the sum of one vector.

• equal to the sum of two or more vectors.

• equal to the difference of one vector.

If two vectors to be added are at right angles, you will need to

• just add them together.

• use the Pythagorean theorem.

• use the Law of Cosines.

• subtract the smaller for the larger.

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
