Data include units SI metric units by default, settable length and mass units. Model overlays are automatically synchronized and scaled to the video for direct visual comparison with the real world.
While these error sources do not usually lead to as much error as is normally found in other timing and position measuring techniques, the introduction of error does make this form of analysis more realistic as a scientific process than do many simulations and MBL probes.
Influence of interactive videodisc instruction using simultaneous-time analysis on kinematics graphing skills of high school physics students. Another free software program, called DataPointis available, but it requires students to import the marked data into a spreadsheet and then manipulate it to produce the relevant information.
Journal of Educational Computing Research, 20 4 The Tracker Web page contains links to tutorials and several video clips ready for analysis. Why do we ask pupils to plot graphs?
Sample videos The Tracker installer includes some videos. The quality of the video is also a factor that influences marking errors.
