Previous Next Parabolic Trajectory # 1D60.60
Description: The pendula show the path of a projectile whose initial angle can be adjusted by pivoting the rod. The length of each dowel is proportional to the square of the distance from the pivot point. Hazards: None. Parts: Parabolic trajectory apparatus Purchased/Built: built Setup Time: 5 min Quant. in Demo Room: 1 Demo References Sutton M-90 A stream of water matches the position of balls of lengths 1,4,9,16,... at all angles of elevation. Freier and Anderson Mb-17 A pivoted bar has pendula of length proportional to the square of the distance from the pivot point. The American Journal of Physics AJP 47(12),1097 Uses the balls hanging from a stick device at the blackboard.
