Momentum, Energy and Collisions
The collision of two carts on a track can be described in terms of momentum conservation and,
in some cases, energy conservation. If there is no net external force experienced by the system of
two carts, then we expect the
Simple Harmonic Motion
Lots of things vibrate or oscillate. A vibrating tuning fork, a moving childs playground swing,
and the loudspeaker in a radio are all examples of physical vibrations. There are also electrical
and acoustical vibrations, such as rad
Rotational Motion
Objectives
Measure the position and velocity as a function of time for an rotating mass
Derive velocity and acceleration vectors and superimpose them on the graph as a
function of time.
Predict the linear direction of the mass when thro
Projectile Motion
You have probably watched a ball roll off a table and strike the floor. What determines where it
will land? Could you predict where it will land? In this experiment, you will roll a ball down a
ramp and determine the balls velocity with
Determining g on an Incline
During the early part of the seventeenth century, Galileo experimentally examined the concept of
acceleration. One of his goals was to learn more about freely falling objects. Unfortunately, his
timing devices were not precise
Modern Galileo Experiment
When Galileo introduced the concept of uniform acceleration, he defined it as equal increases in
speed in equal intervals of time. This experiment is similar to the one discussed by Galileo in his
book, Dialogues Concerning Two N
Energy of a Tossed Ball
When a juggler tosses a bean ball straight upward, the ball slows down until it reaches the top of
its path and then speeds up on its way back down. In terms of energy, when the ball is released it
has kinetic energy, KE. As it ris
Graph Matching
One of the most effective methods of describing motion is to plot graphs of distance, velocity,
and acceleration vs. time. From such a graphical representation, it is possible to determine in
what direction an object is going, how fast it i
