Code Number: 1C10.05
Demo Title: Ultrasonic Detector & Student - Car
Condition: Excellent
Area of Study: Mechanics
Equipment:
Interface with motion sensor, computer, and student, car, or ball.
Procedure:
Have a student stand in front of the motion sensor and move towards or away from the motion sensor to make the position, velocity, or acceleration graphs desired. Holding a square of Plexiglas or other flat reflector against your chest will give a smoother graph.
A car or a ball may be used instead of a student.
