STANDING WAVES
Introduction
In this experiment we study standing waves on a long rubber band stretched between
fixed supports. These standing waves are similar to those produced in a guitar string
when it is plucked, except th

CONSERVATION OF ANGULAR MOMENTUM
Introduction
In this experiment, we first study the relationship between torque, moment of inertia and
angular acceleration, using a rotating platform. We then test the law of conservation of

GAS THERMOMETRY, OR THE QUEST FOR THE
ABSOLUTE ZERO
Introduction
The kinetic theory of gases states that an ideal gas will obey the relation
pV = nRT

ERROR AND UNCERTAINTY
In Physics, like every other experimental science, the numbers we know and the ones
we measure have always some degree of uncertainty. In reporting the results of an
experiment, it is as essential to give the uncertainty,

SIMPLE HARMONIC MOTION
Introduction
In this lab, we study the phenomenon of simple harmonic motion for a mass-and-spring
system and for a variety of pendulums. In a linear mass-spring system, the physical basis

CONSERVATION OF LINEAR MOMENTUM IN
ONE DIMENSION
In this experiment, we study linear momentum conservation in one- dimensional
collisions using the air track. In addition, we study the nature of the principle of actionreaction

CONSERVATION OF ENERGY
Introduction
In this week's lab, we will study the vector nature of force and energy conservation using
a glider on an air track. A vector can be expressed as the sum of its components along a

ACCELERATION
Introduction
In this experiment we determine the gravitational acceleration constant g by measuring the
position of a freely-falling ruler as a function of time.

Dot Product and Cross Products
For two vectors, the dot product is a number
A B = AB cos() = A B = AB
