1. Safety Instructions
This rotating system on air bed is a sensitive
instrument.
• Protect the rotating disc and the air bearing from
mechanical damage.
• Protect the system from dirt, dust and liquids.
When using the laser reflection sensor, the
appropriate regulations for the use of lasers must be
observed.
• Do not look into the laser beam.
2. Description
The rotating system on air bed is an instrument for
the study of frictionless rotational motion,
encompassing the following topics:
Steady rotational motion and rotational motion
with uniform acceleration.
Newton’s laws of motion applied to rotational
motion.
Moment of inertia and torque.
The apparatus is suitable both for presenting clear
demonstrations and for students to investigate the
