Vectors
Coordinate Systems
Used
to describe the position of a point in
space
Coordinate system consists of
A fixed reference point called the origin
Specific axes with scales and labels
Instructions on how to label a point relative to the

Linear Momentum
The
linear momentum of a particle, or an
object that can be modeled as a particle, of

mass m moving with a velocity v is defined to
be the product of the mass and velocity:

Introduction to Energy
The
concept of energy is one of the most
important topics in science and engineering
Every physical process that occurs in the
Universe involves energy and energy

Motion in Two Dimensions
Motion in Two Dimensions
Using + or signs is not always sufficient to fully
describe motion in more than one dimension
Vectors can be used to more fully describe motion
Will look at vector nature of quantities in more de
Chapter 2
Motion in One Dimension
Kinematics
Describes
motion while ignoring the agents
that caused the motion
For now, will consider motion in one
dimension
Along a straight line
Will
use the particle model
A particle is a point-like object, has mass

Physics
Is based on experimental observations and
quantitative measurements.
The main objectives of physics are to identify a
limited number of fundamental laws that govern
natural phenomena
