Rotation Direct Measurement Video

You’ll need to download the videos first and then input them into

  1. Disk accelerated by a rocket motor
  • What is the moment of inertia of the disk?
  • What is the final angular velocity of the disk?
  • What is the average angular acceleration while the rocket is firing?
  • How long was the rocket firing for?
  • What average torque must have been applied to accelerate the disk?
  • What force was provided by the rocket motor?

2. Disk & disk collision

  • Use the video and video analysis to show that angular (rotational) momentum is conserved (or not…)
