Theory
In circular motion, there is no external torque therefore angular momentum L
is conserved , L=iw there fore iowo=ifwf, where i is the moment of inertia and w is the
angular

Vectors
VECTORS
SUMMARY:
Because forces are vectors, a force
table can be used to demonstrate vector
addition. You will measure the force
required to balance two other forces
(so that the three forces sum to zero).
You will also use Excel to add vec

Statistics and Uncertainty
Statistics and Uncertainty
Summary:
You will use coin tosses and measurements of a block of
wood to demonstrate the use of averages, standard
deviations, and measurement uncertainties.
Theory:
One of the most important par

Linear Motion
LINEAR MOTION
Summary:
You will use the computer motion sensor to make plots of position,
velocity and acceleration as functions of time, and compare different
ways of computing velocity from position.
Theory:
Displacement, , is the ne

Measuring g
Summary:
You will measure the acceleration
due to gravity, first by dropping an
object and attempting to time it,
then by using a photogate timer,
and finally by using an inclined
plane.
Theory:
The acceleration due

Simple Harmonic Motion
SIMPLE HARMONIC OSCILLATORS
SUMMARY:
You will determine the spring constant of a spring by observing
the displacement due to various masses. You will then use the
spring and mass as a simple oscillator, and determine

Density and Buoyancy
DENSITY AND BUOYANCY
SUMMARY:
You will measure volumes and masses to compute
density, and measure displaced volumes and
buoyancy forces.

Moment of Inertia
MOMENT OF INERTIA
SUMMARY:
First, you will observe the effects of changes in a
moment of inertia. Then you will measure linear and
angular acceleration to demonstrate the relation
between them, and finally, measure the angu

IMPULSE AND MOMENTUM
SUMMARY:
An accelerated cart is used to compare impulse and
work to change in momentum and energy. Collisions
of carts on a track are measured to demonstrate
conservation of momentum. All the motion is one
