Lab Two - Exercises in Uncertainty
A key concept in any lab science is the uncertainty in measurements. No instrument or
method is a perfect tool. No matter how expensive or advanced it may be, every measurement
will have

Background: In this experiment you will set up forces on a ring using hanging
weights. Since the force is proportional to the weight, we will measure
the forces in the mass units. You will add the forces graphically and

Introduction
Weve studied motion in
one, two, and three
dimensions but what
causes motion?

Newtons Laws of
Motion
This causality was first
studied in the late 1600s by
Sir Isaac Newton.
The laws are easy to state
but intricate

Purpose:
To measure the acceleration of gravity using an Atwoods machine.
Description:
In order to slow down a falling object, we need to apply a force to the object in the
upward direction. This c
Rotational Inertia
In this lab we will use a small hanging weight to accelerate a pair of masses about their
axii of rotation. We'll use a stopwatch and a ruler to make measurements of the moment
of inertia in today's lab. As your pre-lab exercise, use to
