Condition :   Good   
Principle :   Velocity, Position, Acceleration  
Area of Study :  Mechanics  
Equipment :   Two Incline Plane Tracks, One Inch Steel Balls, Ball Catchers, Photogates, Computer with Interface.
Procedure :   Mount the tracks so that one track has four times the height of the other.  20 cm and 80 cm seems to work well.  Place the Photogates at the same height at the ends.  Velocity time should be double for the track that has four times the height.
