Ch 3 Introduction
Many quantities in physics require that a
direction be specified in addition to magnitude.
These quantities are called vectors. Here, we
learn about the properties of these mathematical
objects, and how they can be combined one with
another.

Where were going
Ch 3 Vectors (3.1) Coordinate Systems (3.2)
Vector Scalar Quantities (3.3) Some Properties
of Vectors (3.4) Components of a Vector
6
3.1 Coordinate Systems

• Cartesian (x,y) Rectangular (x y)
• Polar (r,?)

7
3.2 Vector Scalar Quantities

• Vector vs. Scalar

8
3.3 Properties of Vectors

• Laws pg. 61-64 (see highlight pg. 61)
• OK to move vector parallel to current position
• Negative of vector A (-A) 0
• Subtraction A B A (-B)
• Multiplication if A

, then 5A
And 5A
