Chapter 2: Kinematics: Description of Motion Objectives

• What is displacement and how does it help me describe the world around me?
  
  
• What is the difference between average speed and average velocity? I thought they were the same.
  
  
• Speed and velocity can both change. How do I find instantaneous speed and instantaneous velocity?
  
  
• What is acceleration and how is it calculated?
  
  
• If acceleration is constant how can I describe motion?
  
  
• The mystery of problem solving—how do I do it?
  
  
• Up and down, the rise and fall of bodies—how do I master this motion?
  
  
• How can graphs help me understand this chapter?

NOTE:

The recommended system requirements to use the applets in the Physlets® modules are:

• a Pentium 90 with 16MB RAM or Power Macintosh with 32MB 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.
