Vector Description

• A vector is a quantity that requires both
  magnitude and direction
• Magnitude is the size (the number) with units.
• Direction is the direction the vector is pointing
  based on the assigned coordinate system.

Vector Description

• The magnitude answers the question How big
• The direction answers the question Which way

• Velocity
• Acceleration
• I.Q.

Add Vectors

• Add the same type of vectors only!
• Add vectors head to tail.
• The result is the vector drawn from the tail of
  the first to the head of the last vector.

Graphical Addition

• Draw each vector to scale Magnitude and
  Direction.
• Begin with the first.
• At the head of the first place the tail of the
  second (head to tail method) and so on.
• Vectors can be added in any order.
