In this activity,  students will use a TNS file for visualizing the velocity and acceleration vectors at specific times associated with a particle as it moves along a curve. 

This TNS file provides a technology tool for visualizing the velocity and acceleration vectors at specific times associated with a particle as it moves along a curve. The velocity and acceleration vectors are computed automatically.  The complete curve can be displayed or the moving point alone can be displayed (the geometric trace option is used in this case).  The velocity and acceleration vectors can be shown or hidden.
