The Physics Classroom - Scalars and Vectors

We decided that we are going to be studying physics to better understand multiplicity.  We found a very good online site for high school level physics.  All physics quotes and pictures will come from "The Physics Classroom."  Physics Classroom Table of Contents.  You will always know we are using this resource, because we will title the entry, "The Physics Classroom."  Our Jamie will be in charge.

The first section is called, "kinematics."  The resource says this is, "the science of describing motion of objects using words, diagrams, numbers, graphs, and equations."  They say that studying kinematics will help us understand, "the motion of real world objects."

"The motion of objects can be described by words - words such as distance, displacement, speed, velocity, and exceleration.  These mathematical quantities which are used to describe the motion of objects can be divided in two categories.  The quantity is either a vector or a scalar.  Scalars are quantities which are described by a magnitude alone.  Vectors are quantities which are described by both a magnitude and a direction."

Hmm, better look up magnitude ... Ok, it's a spacial quality or size like miles, miles per second, degrees celsius, bytes, or calories.  By adding a direction, they mean like north, south, west, or east.  So that 5 miles would be a scalar and 5 miles east would be a vector.

We figure the main objects that we will want to be figuring out are our Dear Heart (core), our attackers (sexual, physical, emotional, or spiritual abusers), the buckets (our multiple parts), the rope and pulley (?), the rocks (memories and feelings), and the geologist mining the rocks in the bucket (the good Dr. M.).

That would mean a scalar could be like 15 feet, and a vector could be 15 feet north.  Hmm, could a vector be a direction like, "up?"  [Check this out.]  We figure that our buckets are about 15 feet up above Dear Heart's head.
