Temperature, Internal Energy, and Ideal Gases
Motivation:
Build foundations for heat transfer and
the laws of thermodynamics
Objectives:
Identify the mechanism of energy flow and understand when temperature
can change.
Distinguish between mechanical energ
Tension
Motivation:
Ropes, cables and strings are used in many
devices. We must learn how to describe them.
Objectives:
Learn the properties of ideal strings
Draw accurate free body diagrams for systems containing strings
Solve problems involving objects
Thermodynamic Cycles & Heat Engines
Motivation:
Understanding how heat engines convert heat to mechanical
work.
Objectives:
Learn what a heat engine is and how its efficiency is defined.
Analyze a simple heat engine and determine its efficiency.

Vector Algebra
Motivation:
We must learn how to mathematically manipulate vectors,
since we will need to do this all semester.
Objectives:
Learn how to perform algebraic operations with vectors and scalars
Analyze word problems in 2D motion and convert th
Vectors
Motivation:
Many physical quantities that we will be studying
are vectors. We need to know how to interpret and
use them.
Objectives:
Describe vector quantities from two complementary perspectives:
(1) magnitude and direction; (2) components
Learn
Describing 1-D Motion
Motivation:
We will be analyzing moving objects all
semester. In this section, we are describing
how they move (not why). This is what we
call kinematics.
Objectives:
Learn definitions, both numerically and graphically, of displaceme
Waves
Motivation: Energy is frequently transferred through systems in the form of
a wave. We need to understand how to describe them.
Objectives:
Learn to distinguish between transverse and longitudinal
waves.
Learn the parameters describing a periodic wa
