investigation of uniformly accelerated rotational motion

Description:

• The resistance with which a rigid body opposes a change to its rotation is indicated by the mass moment of inertia.
• It is a measure of the inertia of a body in rotation.
• Using the TM 612kinetic model, we can conduct basic experiments on uniformly accelerated rotational motion.
• The experimental unit comprises a flywheel with shaft, a cable and a set of weights.
• The shaft forms the axis of rotation in the centre of gravity of the flywheel.
• It is mounted on two bearings.
• One end of the cable is attached to the shaft.
• A weight is attached to the other end.
• The attached weight sets the flywheel in a uniformly accelerated motion.
• The time needed to roll down is measured and compared to the times for other weights.
• The mass moment of inertia of the flywheel is calculated from the measured time, the mass of the flywheel and the acceleration distance.
• The experimental unit is designed to be fixed to a wall.
