After studying this chapter, you should:

know the definition of linear momentum and how it relates to force.

know the meaning of impulse and how it relates to linear momentum.

be able to use linear momentum to analyze elastic and inelastic collisions.

be able to determine the location of the center of mass of a system.

be able to apply Newton's laws to a system of particles.

understand the basic principles behind rocket propulsion.

NOTE:

In order to take advantage of the new features in Java, the Physlets® module uses the the new release of the JDK, JDK 1.1.
Currently, the new version of Java is supported on PCs. running Win95/98/NT.
Note to Mac users: Currently, Physlet® Problems will not run on a Macintosh Power PC since the major browsers for this platform do not support both Java 1.1 and Java to JavaScript communication.

There is an alternative for experienced Mac users, if they are adventuresome. The HotJava browser from Sun Microsystems (http://www.java.sun.com/products/OV_hotjavaProduct.html) freely available is a temporary solution that supports both Java 1.1 and JavaScript to Java communication. Make sure you are using the latest MacOS Runtime for Java (MRJ) available at http://www.apple.com/java/. Send questions to Carl@CarlAdler.org .
In addition, on PCs, the new version of Java works best with the Internet Explorer 4 web browser or higher.
If you are using a PC running Win 95/98/NT and are using Netscape, please download the latest version of Netscape.
The recommended system requirements to use the applets in the Physlets® modules are:

a Pentium 90 with 16MB RAM
either Netscape 3.0.3 and higher or Internet Explorer 4.0 or higher. Internet Explorer 3.0/AOL browser does not work!
Your internet connection should be through your school's local area network. Using a 28.8 modem will result in dramatically increased load times.
