Two-Dimensional Kinematics Review

If two vectors are given such that A + B = 0, what can you say about the magnitude and direction of vectors A and B?

• same magnitude, but can be in any direction
• same magnitude, but must be in the same direction
• different magnitudes, but must be in the same direction
• same magnitude, but must be in opposite directions

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
