Specific Heat and Latent Heat
Motivation:
Many processes require raising or lowering the temperature
of some substance. We need to understand how much
energy that requires.
Objectives:
Determine the e
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 defin
Newtons Laws of Motion
Motivation:
We have covered kinematics, so we now know how to
describe motion. We now need to understand why an
object moves in that particular way; that is, we want to

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 longitudin
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 perspect
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 sc
