Description: 

A small weight wound around a disk causes it to rotate. Science Workshop software is used to measure the acceleration of the weight.

Instructions: 
  • A film strip acts as a photogate "fense" and is inserted into a slit on the disk.
  • A 3g paper clip is attatched to the end of the film strip as a weight.
  • The plunger is engaged to hold the disk still until you are ready to start the demo.
  • Simultaneously click "monitor" in the Science Workshop window and pull the plunger to release the disk. The linear acceleration is measured as the disk rotates.



    • Pulley Mass = 3.6275 Kg
    Pulley Radius = .1025 m
    Clip Mass = 2.95 g
    Tape Spacing = 1.52 cm or .148 radians

    Purpose: 
    The purpose is to show the relationship between rotational kinematics and rotational kinematics.
