2.  Persistence of Vision-The way our eyes retain images for a split second longer than they actually appear, making a series of quick flashes appear as one continuous picture.  Frame-by-Frame Animation-A series of many frames that appears to be in continuous motion.

3.  Path Based Animation-Also called vector animation. The user inserts an object and draws a path (or vector). The computer tweens, or creates the frames, to move the object along the path.  3d Graphics-The field of computer graphics concerned with generating and displaying three-dimensional objects in a two-dimensional space

4.  Rollovers-The look or action of a control with relation to mouse actions. The four common rollover states are Up, Over, Down, and Hit.  Morphing-A technique in which one image is gradually turned into another, which is short for metamorphosing.

5.  Stage-The part of the animation program window where the animator's content is composed and manipulated.  Frame-A single still image in a video animation.  Keyframe  An intermediate frame in an animation sequence that blends so one frame appears to change into the next.

6.  Timeline-The part of the animation program window that organizes and controls an animation's content over time using layers and frames.  Library-Store frequently used graphics, movie clips, and buttons.  Playhead  The vertical red marker in the timeline that shows which frame is the current frame.

7.  Scrub-Dragging the playhead across the timeline.  Tween(ing)-An animation process that uses keyframes between two images.  Compression-The process of reducing the space required to store data be efficiently encoding the content

8.  MP3-A standard format for music files sent over the Internet that compresses music.  WAV-The standard format for sound files on Windows PCs.  Executable-A program file that can run on your computer.

9.  Plug-in-A hardware or software application that adds a specific feature to a computer.  QuickTime-A cross-platform multimedia format that works on both Microsoft Windows and Apple Macintosh systems.  Stand Alone Player-A separate program that can play an animation.

10.  Bandwidth-The amount of data that can be transmitted over a network in a given amount of time.  Streaming-A procedure for transmitting media files so they can start playing as soon as a PC begins receiving them, rather than waiting for the complete files to download first.  Streaming Rate-The rate in frames per second at which the movie can be downloaded.

11.  Playback rate-The rate in frames per second at which the movie plays.  Programming or Scripting-Based Animation- Requires knowledge of programming or scripting languages.  Stop Motion Animation-Manipulating real- world objects and photographing them one frame at a time. Example: Clay Animation
